Highlights of Solar and Geomagnetic Activity
09 - 15 June 2008
Solar activity was very low. No flares were detected. The visible solar disk was spotless until 11 June when Region 998 (S09, L = 291, class/area, Cro/040 on 10 June) was numbered. This region decayed to spotless plage on 14 June, and was still on the visible solar disk as the summary period ended.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels through the period.
Geomagnetic field activity was at quiet levels from 09 June through midday on 14 June. Wind speed measurements from the ACE spacecraft were declining from around 450 km/s at the beginning of the period to about 300 km/s early on 14 June. A co-rotating interaction
region was observed on 14 June at approximately 1130Z. Soon thereafter, geomagnetic activity increased to unsettled to minor storm conditions, and remained at this level through 15 June. Wind speeds quickly increased to just below 700 km/s with interplanetary magnetic field Bz component values ranging between +13 and -17 nT. Early on 15 June a transition into a recurrent coronal hole high speed stream occurred. This continued through the end of the
summary period as wind speeds stayed around 650 km/s.
Forecast of Solar and Geomagnetic Activity
18 June - 14 July 2008
Solar activity is expected to be very low.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels during 18 - 23 June and again on 13 - 14 July.
Geomagnetic field activity is expected to be at unsettled levels during 18 - 20 June due to a recurrent coronal hole high speed stream. Activity is expected to decrease to quiet levels during 21 - 24 June. Activity is expected to increase to unsettled levels during 25 - 27 June again due to a recurrent coronal hole high speed stream. Activity is expected to decrease to quiet levels during 28 June - 02 July as the coronal hole rotates out of a geoeffective position. Activity is expected to increase to unsettled levels during 03 - 05 July due to another coronal hole high speed stream. Activity is expected to decrease to quiet levels for 06 - 10 July. From 11 July through the end of the period expect unsettled to active conditions due to a coronal hole high speed stream.
