#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 06 - 12 May 2019

Solar activity was at low levels on 06, 07, and 09 May due to C-class flare activity from Region 2740 (N08, L=307 class/area Dho/280 on 05 May. The largest of the flares was a C9.9/1N at 06/0510 UTC. Mutliple eruptions were observed in coronagraph imagery, but only the halo CME from 06 May was geoeffective. The assymetric halo CME was first observed in SOHO LASCO C2 imagery at 06/2348 UTC. Additionally, a partial halo CME was first observed in LASCO C2 imagery at 12/2036 UTC and is determined to be Earth-directed and arrive at Earth on 17 May. Solar activity was at

very low levels for the remainder of the summary period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 07, 11, and 12 May. Normal to moderate levels were observed throughout the remainder of the period.

Image Reports

April 2019's regions

Region 2740 was April 2019's big surprise and 2nd return! This region, return of AR 2736 (N06-298), here max 350mvh on 2019 April 10 (1630 UTC), travelled all the way from east to west and apparently

did not decay at all.

The classifications for the region kept up at a HHX or CHO throughout the entire transit! More in next issue!

The recent activity on the sun has sent the Flux 10,7 cm 2800 MHz measured at Penticton, Canada, upwards. Theory is that the levels experienced March-May 2019 will end. All forecasts point to a minimum March/April 2020.
