Solar flare activity was low during 7 May UT. Active Region (AR) 2339
produced seven C class flares and has the potential to produce M class
flares in coming days. AR 2335 is decaying and produced no noteworthy
flares during 7 May. H alpha solar telescope observations recorded the
disappearance of a large, unstable solar prominence in the
geoeffective sweet spot west of the solar meridian during 15 UT on 6
May. SOHO coronograms are now available and they show a weak partial
halo CME associated with this event. This CME may impact Earth on 10
May. A minor geomagnetic storm (G1) is possible during 10-11 May.
Another very weak CME may arrive at Earth on 9 May and drive unsettled
geomagnetic conditions on 9 May. The solar wind speed is presently
abating and geomagnetic conditions are expected to be very quiet
today, 8 May. Conditions for HF radio propagation are expected to be
near predicted monthly values during 7-8 May.
