#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 06 - 12 July 2020

Solar activity was very low throughout the summary period. Region 2766 (N05, L=122, class/area Bxo/010 on 10 Jul) was the only spotted region and decayed to plage by 11 Jul.

A filament eruption near S29W18 produced a faint, slow-moving CME signature in LASCO/SOHO C2 imagery beginning at 09/0724 UTC. Analysis and modeling of the event suggested a possible glancing blow from the CME around 14 Jul.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the summary period.

Geomagnetic field activity was quiet. No significant periods of southward Bz were observed.

May 2020 news

No significant solar regions were visible during May 2020. June more promising... next issue. NOTE! Heading: We anticipate that we may say hello to Solar Cycle 25, hence Month no. 6

hence we chance to call May 2020 Month no. 6 in the new cycle!
