Here is this week's space weather and geophysical report, issued 2021 Jun 07 0121 UTC.

Highlights of Solar and Geomagnetic Activity 31 May - 06 June 2021

Solar activity was at very low levels on 31 May, and 02-06 June while low levels were reached on 01 June. The majority of the flare activity, including the C1.6 flare on 01 June, was caused by Region 2827 (N11, L=78, class/area Dso/110 on 31 May). B-class activity was observed by Regions 2828 (S31, L=69, class/area Axx/10 on 31 May) and 2829 (S18, L=12, class/area Cro/30 on 05 June).

No proton events were observed at geosynchronous orbit.

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

Geomagnetic field activity was quiet to unsettled for the highlight period with no significant activity.

Forecast of Solar and Geomagnetic Activity 07 June - 03 July 2021

Solar activity is expected to be at very low to low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 11-14 June and 20-22 June due to recurrent coronal hole high speed stream (CH HSS) influences.

Geomagnetic field activity is expected to be at unsettled to active levels on 08 June and 16 June due to recurrent CH HSS influences. Quiet to unsettled levels are expected for the remainder of the outlook period.
