Here is this week’s space weather and geophysical report, issued 2015 Jun 01 0141 UTC.

Highlights of Solar and Geomagnetic Activity 25 – 31 May 2015

Solar activity was at very low levels for the majority of the period with the exception of 27 May when low levels were observed. The period was dominated by only low-to-mid level B-class flares with an isolated C1 flare at 2131 UTC on 27 May. The only C-class event of the period originated from Region 2456 (S16, L=199, class/area=Cso/70 on 30 May) but no coronal mass ejection (CME) was observed with this event. Multiple prominence and filament eruptions were observed throughout the period but none resulted in Earth-directed CMEs.

No proton events were observed at geosynchronous orbit.

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

Geomagnetic field activity was generally quiet throughout the period with an isolated period of unsettled activity observed between 27/1200-1500 UTC.

Forecast of Solar and Geomagnetic Activity 01 June – 27 June 2015

Solar activity is expected to be very low with a chance for C-class flare activity throughout the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate levels on 15-19 Jun and high levels on 10-14 Jun with normal levels expected for the remainder of the period.

Geomagnetic field activity is expected to be at active levels on 10 and 14-15 Jun with G1 (Minor) geomagnetic storms likely on 08-09 Jun, all in response to recurrent coronal hole high speed stream influence. Quiet to unsettled geomagnetic field activity is expected for the remainder of the period.
