Highlights of Solar and Geomagnetic Activity 01 - 07 June 2020
Solar activity was at very low levels with numerous B-class flares observed from new Region 2765 (S24, L=116, class/area Cao/130 on 05 Jun). This reverse polarity region was mostly stable since it rotated onto the disk on 03 Jun. No Earth-directed CMEs were observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels through the period.
Geomagnetic field activity was at mostly quiet levels, with some isolated unsettled periods late on 01 Jun through early 02 Jun. A nominal solar wind environment was prevalent with wind speeds that were ranging from 300-400 km/s, total field (Bt) 5 nT or less and the Bz component mostly neutral.
Solar wind parameters became enhanced after midday on 07 Jun. Wind speeds increased to near 475 km/s, Bt reached a maximum of 13 nT and Bz reached a maximum southward extent of -8 nT. A suspected weak, positive polarity CH HSS resulted in this enhanced wind environment. The geomagnetic field reacted with unsettled to active conditions the last half of 07 Jun.
Forecast of Solar and Geomagnetic Activity 08 June - 04 July 2020
Solar activity is expected to be at mostly very low levels. A slight chance of low level activity exists through 15 Jun while Region 2765 remains on the visible disk. Very low levels will then persist through 28 Jun. Old Region 2765 (S24, L=116) is expected to return after 28 Jun with a possible increase in low level flare activity to a slight chance.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels through the outlook period.
Geomagnetic field activity is expected to be at unsettled to isolated active levels on 08 Jun due to the influence from a weak, positive polarity CH HSS. From 09 Jun to 04 Jul, mostly on quiet levels that are anticipated.
