Highlights of Solar and Geomagnetic Activity 08 - 14 June 2026

Solar activity was at low levels the entire period, with only C-class flares observed. There were five flares at or above the C5 level, with all but one originating from Region 4465 (N09, L=292,

class/area=Dhi/255 on 11 Jun). These included: a C7.2 at 09/0249 UTC, a C6.7/1f at 11/0026 UTC, a C9.0 at 11/0828 UTC (the largest of the period), and finally a C5.2 flare at 12/0214 UTC. The only other flare greater than C5 was a C6.1 flare at 11/0044 UTC from Region 4456 (N17, L=63, class/area=Dai/80 on 08 Jun). 

Additional activity included a type-II radio sweep at 09/1557 UTC, with an estimated velocity of 917 km/s, likely associated with low-level C-class flaring from Region 4463 (N16, L=339, class/area=Hsx/70 on 10 Jun). An associated CME was first observed in the NE quadrant of LASCO/C2 around 09/1630 UTC, which correlated to an eruption near (and south of) Region 4463. Analysis suggested glancing effects near-Earth on 13-14 June. A second type-II sweep (est. velocity = 1,127 km/s) was detected by the RSTN stations at 10/1715 UTC. An associated CME was first observed in the NE quadrant in LASCO/C2 imagery at 10/1800 UTC, with modeling and analysis indicating no Earth-directed component was likely. The third and final type-II sweep of the period was associated with the C6.7/1f flare from Region 4465 observed at 11/0002 UTC, and had an estimated velocity of 918 km/s. Additionally, a type-IV radio sweep and a partial halo CME were observed, with analysis indicating potential impact near-Earth starting early on 13 Jun. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 08-10 and 13-14 Jun, with a peak flux of 4,259 pfu at 09/1525 UTC. Flux levels were low to moderate on 11-12 Jun. 

Geomagnetic field activity was at quiet to unsettled levels on 08-10 and 14 Jun under nominal conditions. Active to G1 (Minor) storm conditions were observed on 11 Jun with unsettled to active

conditions observed on 12-13 Jun under negative polarity coronal hole high speed stream (CH HSS) influences, combined with weak CME effects, likely associated with the CME that left the Sun on 09 Jun. 

Forecast of Solar and Geomagnetic Activity 15 June - 11 July 2026

Solar activity is expected to be at mostly low levels through 19 Jun, with increasing chances for M-class activity after 20 Jun with the anticipated return of Region 4455 (N14, L=88, class/area=Dki/360

on 03 Jun) 

No proton events are expected at geosynchronous orbit, barring significant flare activity. 

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 15-17 Jun and 04-10 Jul. Normal to moderate levels are expected to prevail throughout the remainder of

the period. 

Geomagnetic field activity is expected to be at quiet to unsettled levels on 15, 17-24, and 26-30 Jun, as well as 01-02, 04-07, and 10-11 Jul. Active conditions are likely on 16, 25 Jun and 03

08, and 09 Jul under elevated CH HSS influence.

Memories of Radio Broadcasting in Portuguese Goa

 

This program originally aired on October 1, 2000

The one-time Portuguese colony of Goa lies on the western coast of India, nearly half way from Bombay to the southern tip of the peninsula.  This small territory was settled by the Portuguese in the year 1510 and was re-incorporated into India in December 1961.

Goa is a fascinating place to visit, with its extended miles of wide ocean beaches, its varied coastal and inland scenery, and its tropical and sub-tropical fruits.  To this day, Goa still exudes a subtle evidence of its earlier European culture, with its Latin-style church architecture, its European style of dress, its Portuguese Konkani music, and the occasional usage of the Portuguese language.

On many occasions, I have visited favored Goa.  I have swum at its beaches, I have jogged the entire 65-mile coastline, I have shopped in its exotic bazaars, I have eaten in its restaurants, and I have visited its radio stations.

It was back on May 28, 1946, that the first experimental radio broadcasts went on the air in old Goa.  This radio program service was broadcast from a 500-watt transmitter operated by the Post & Telegraph Office.  It was on the air for only a short period of time.

A regular broadcasting service was inaugurated in 1949 using a temporary 1 kW. shortwave transmitter in Panjim, the small capital city.  This unit was located at the radio studios of what became Emissora de Goa, on a hill overlooking the city.  The current studios and offices of All India Radio in Goa incorporated the older studio buildings at the same site.

Classic AIR QSL via Goa

During the following year an additional 2.5 kW. A mediumwave transmitter was installed at the studio location, and a country transmitter base was constructed some 6 miles from Panjim.  Over a period of time, two shortwave transmitters and one mediumwave transmitter were installed at this country location.

During the year 1961, a 50 kW. A shortwave transmitter was installed, and this unit made test broadcasts on three different channels, beamed towards Africa, the Persian Gulf, and the Far East.

With the changing winds of fortune, Emissora de Goa finally left the air and closed down forever at 8:00 am on December 18, 1961.  Less than two months later, All India Radio came on the air from the same studios, though with only one transmitter, the 5 kw. mediumwave unit on 880 kHz.

It should be remembered that the first broadcasts in Southern Asia of the familiar AWR program, "Voice of Prophecy," went on the air from station CR8AA, the old Emissora de Goa, in the year 1950.  The half-hour broadcasts of the English language "Voice of Prophecy" were on the air from Goa for two years, though this programming was subsequently transferred to the Commercial Service of Radio Ceylon in Colombo.

So what happened to Emissora de Goa, R. Goa afterwards?  Well, the studios and offices on the hill overlooking Panjim have been rebuilt twice and are in use today by All India Radio.  There is a new shortwave base out in the country containing two transmitters at 250 kw. which are in use for the General Overseas Service of All India Radio.  And what about the old radio base out in the country?  I visited this location many years ago, and all that was left at that time was some wreckage from one of the old buildings and lots of overgrown grass.

Closing Days of Canada's CHU

 

Canada’s Time Signal Station CHU Ottawa to Cease Shortwave Transmissions in June 2026.

On June 22, 2026  the National Research Council Canada, known as the NRC, will permanently discontinue the shortwave broadcasting operations of its official time signal station, CHU.

From that day forward, the familiar frequencies of 3330 kHz, 7850 kHz, and 14,670 kHz will fall silent. For the future, the NRC points matter - of factly to modern alternatives: the Network Time Protocol (NTP) for computers, web-based clocks, and the traditional telephone service.

The history of CHU stretches back an astonishingly long way to an era when radio itself was still in its infancy. It all began in 1923 under the aegis of the Dominion Observatory in Ottawa. The initial experimental broadcasts were transmitted under the call sign 9CC on the longwave band at 275 meters.

Anyone who has not yet sent a reception report to Ottawa should make use of the time remaining until June. The NRC has confirmed that valid reports will continue to be acknowledged with the traditional CHU QSL card. Fittingly, the card features an image of Sir Sandford Fleming, the Canadian railway engineer and "father of worldwide time zones".

Reception reports may be sent via email or, in the classic tradition, via postal mail to:

Radio Station CHU, 1200 Montreal Road, Building M-36, Ottawa, Ontario,

K1A 0R6, Canada, North America.

Email: radio.chu@nrc-cnrc.gc.ca

Wavescan presents, Mary Texanna Loomis, Radio Pioneer

 Special thanks to the Wavescan staff for this week's feature from a Texas radio pioneer

Jeff:   Most features we present on the history of broadcast radio, and shortwave in particular, seem to feature men.  But we would be remiss in not mentioning that there were also a number of female pioneers involved in the early days of radio, and today, Ray Robinson in Los Angeles has the story of one of them.

Mary Texana Loomis and one of her transmitter projects

Ray:  Thanks, Jeff.  Yes, today’s feature is about Mary Texanna Loomis, who in 1920 founded the Loomis Radio School in Washington, D.C.  This topic was suggested by Wavescan listener Martin Dawson on Prince Edward Island in Canada, after he had read an old article in Radio World which in turn had been sourced from articles in several old magazines and newspapers of the 1920s and 30’s.

In the 1920s, if you wanted to get a job in America as a commercial radio operator or a shipboard radioman on an American vessel, you needed a Commercial Radio License, issued by the U.S. Department of Commerce.  The best way to obtain such a license was to attend one of the few radio schools that operated in principal cities around the United States.  Two of the most distinguished schools were in Washington, D.C.:  the National Radio Institute and the Loomis Radio School.  The latter was the only woman-owned radio school in the country.  Mary Texanna Loomis was the principal instructor and that rare creature in the 1920’s:  a female authority on radio.

Mary was a distant cousin of Dr. Mahlon Loomis, who in 1866 had experimented with ‘stealing current from the atmosphere’ using kites and metallic string.  In one experiment, he flew kites from two peaks of the Blue Ridge Mountains in Virginia and, using a galvanometer, was able to detect a change in current in one kite when he grounded the line of the other.  Subsequently, he was able to send Morse Code messages between the two locations, a distance of 18 miles.  And that experimentation in wireless communication took place a full nine years before Guglielmo Marconi was even born.

Mary Texanna Loomis was born on August 18, 1880, in a homesteader’s shack near Goliad, Texas, the second child of Alvan and Caroline Loomis.  Her middle name, ‘Texanna’, was bestowed in honor of the state where she was born.

Mary Texanna Loomis

The family moved to Rochester, N.Y., in 1883, where she had a respectable middle-class upbringing.  She was sports-minded in her youth, participating in swimming and horseback riding.  She also took voice lessons and became a good soprano.  She learned to speak three languages:  French, Italian and German.  A grandfather was a strong influence; he taught her to use tools and to build mechanical devices, and he helped develop her interest in science and the new inventions of the industrial age.

Mary Loomis married Turner Erving Howard in October, 1898, in Buffalo, NY.  Sadly, the marriage ended in divorce in 1917, and there’s no record that they had any children.  Mary then reverted to her maiden name of Loomis.

After her divorce, Mary moved to Washington, where she looked unsuccessfully for music employment.  But her life took a new turn when she attended a lecture on the emerging technology of wireless communication.  Fascinated, she read everything she could find on the subject.  At the age of 38, at a time when radio was the field of only a few experimenters and inventors, most of them men, she graduated from radio school and earned her first-class radio telegraphy license.

During World War I, she worked for the Red Cross and also as a secretary in a wireless school.  It was only then that she learned about the experiments of her distant cousin, Mahlon Loomis, and she resolved to open a radio operator’s school in his honor.

In 1920, she invested every cent she had and incorporated the Loomis Radio School. Located at 401–411 Ninth Street in the northwest quadrant of Washington, D.C., it offered a six-month course preparing students for the first-class commercial radio license exam.  Most students who graduated found positions as shipboard radio operators.  Loomis was the school’s president and principal lecturer.  She taught radio using equipment she constructed herself in the school’s machine shop, and taught her students not only how to operate, but also how to build radio equipment.  “No man can graduate from my school until he learns how to make any part of the apparatus,” she said.  “I give him a blueprint of what I want him to do and tell him to go into the shop and keep hammering away until the job is completed.  I want my graduates to be able to meet any emergency or mishap that may arise someday far out on the sea.”

The Loomis Radio School in Washington, D.C.

She lived a frugal life in a boarding home, and worked 12 to 15 hours a day teaching, grading papers and writing.  In time, the Loomis Radio School offered four courses, with the main one (for would-be commercial radio operators) leading to a first-class commercial radio operator's license.  A second course for technical training taught how to build a receiving set.  A third course led to a license as an amateur radio operator, and the fourth was for operators who needed only to renew an expired license or who had been military operators and needed only minimal training.

Her students also gained practical experience operating a radio transmitter through the use of the school’s amateur station, W3YA.  Loomis was a noted lecturer and member of the prestigious Institute of Radio Engineers.  She authored and marketed the popular book “Radio Theory and Operating for the Radio Student and Practical Operator.”  This was a reference text of 886 pages with 700 illustrations.  It was advertised at a reasonable price and was offered postage-paid directly by the school.  It subsequently became a textbook used by many educational institutions and government agencies.

By 1928, the Loomis textbook was in its fifth edition, then amounting to 1,006 pages.  “Radio Broadcast” Magazine called it “one of the most comprehensive volumes in its field.”  Mary dedicated her book to her cousin Mahlon Loomis.

Loomis teaching a class of future radio operators

The depression that began in 1929 affected the school severely, as it did tens of thousands of other businesses.  Fewer students could afford the training, and larger schools like the National Radio Institute had more resources to weather the hard times.  Further, a new competitor, the Capitol Radio Institute, would open in Washington in 1932.  In 1930, Loomis reorganized the school as the Loomis Radio College, Inc., but it was dissolved in early 1933.

Not much is known about Mary’s later life.  She is known to have relocated to San Francisco in 1938; the census shows that she lived in the St. Francis Hotel and listed her occupation as a stenographer.  Mary Texanna Loomis died in that city in June 1960 at the age of 79, and was buried at the Woodlawn Memorial Park in Colma, California.

Back to you, Jeff.

Jeff: Thanks, Ray.  And in a few weeks’ time, Ray will have a story about another woman who was active in early radio – Mary Day Lee.

Solar activity reached high levels on 03 Jun when Region 4455 (N14, L=88, class/area=Dki/360 on 03 Jun) produced an M9.3/Sf flare (accompanied by Type-II (253 km/s) and Type-IV sweeps, and a 360 sfu Tenflare) at 03/0136 UTC, followed by an M7.7/1b flare (accompanied by Type-II (313 km/s) and Type-IV radio sweeps, and a 540 sfu Tenflare with Castelli-U signature) at 03/0700 UTC, and finally an

X1.0/1n flare (accompanied by a Type-IV sweep and a 180 sfu Tenflare) at 03/1128 UTC. The CMEs associated with the three significant flares from AR4455 on 03 Jun arrived at Earth on 05 Jun.

Other activity included an M1.8/2n (accompanied by Type-II (838 km/s) and 190 sfu Tenflare) flare at 06/1401 UTC from Region 4461 (S20, L=09, class/area=Dao/70 on 02 Jun). The resulting partial-halo

CME, first visible in LASCO C2 imagery at 06/1401 UTC, is anticipated to arrive at Earth around midday on 08 Jun. 

The greater than 10 MeV proton flux became slightly enhanced after midday on 06 Jun, following the M1.8/2n flare at 06/1401 UTC from Region 4461, but remained below event levels with a peak flux of 1.0 pfu observed at 06/1940 UTC. The greater than 10 MeV proton flux gradually returned to background levels on 07 Jun. 

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels on 01-05 Jun, with high levels observed on 06-07 Jun. 

Geomagnetic field activity reached G1-G2 (Minor-Moderate) storm levels on 05 Jun, and active levels on 06 Jun, following the arrival and passage of the CMEs from 03 Jun. The shock arrival was observed

beginning at around 05/0425 UTC, and in the hours following, the total magnetic field strength (Bt) reached 20 nT, the Bz component reached as far southward as -17 nT, and solar wind speeds increased

to a peak near 740 km/s. Quiet and quiet to unsettled levels under weak coronal hole high-speed stream influences prevailed throughout the remainder of the period. 

Forecast of Solar and Geomagnetic Activity 08 June - 04 July 2026

Solar activity is expected to be at predominantly low levels through 04 Jul, with M-class flare probabilities ranging from a chance to likely levels throughout the period. 

No proton events are expected at geosynchronous orbit, barring significant flare activity. 

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 09-10, 13-18 Jun and 04 Jul. Normal to moderate levels are expected to prevail throughout the remainder

of the period. 

Geomagnetic field activity is likely to reach G1-G3 (Minor-Strong) storm levels on 08 Jun, with G1-G2 (Minor-Moderate) levels likely on 09 Jun, due to the anticipated arrival of the CME that left the Sun

on 06 Jun. Periods of active conditions are likely on 23-26 Jun due to recurrent CH HSS influences. Quiet and quiet to unsettled levels are expected to prevail throughout the remainder of the period.
