Highlights of Solar and Geomagnetic Activity
25 - 31 May 2009
Solar activity was very low. No flares were observed. New cycle polarity Region 1019 (N28, L=297, class/area Cro/080 on 02 June) was numbered on 31 May. It was simply structured and produced no flares during the summary period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels during the period.
Geomagnetic field activity was at quiet levels at all latitudes during most of the period. However, activity increased to unsettled levels on 28 May with a brief period of active levels at high latitudes. The increase followed a sudden impulse at 28/0520 UTC (33 nT, as observed by the Boulder USGS magnetometer). ACE solar wind measurements indicated an interplanetary shock passage at approximately 28/0418 UTC. There was no obvious source for the shock. Solar wind changes associated with the shock passage included a jump in velocity (284 - 338 km/sec at 28/0418 UTC), increased interplanetary magnetic field (IMF) Bt (peak 12 nT at 28/0722 UTC), and intermittent periods of southward IMF Bz (minimum -8 nT at 28/0857 UTC).
Forecast of Solar and Geomagnetic Activity
03 - 29 June 2009
Solar activity is expected to be very low.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal flux levels.
Geomagnetic field activity is expected to be at quiet to unsettled levels during 03 - 04 June. Mostly quiet conditions are expected during 05 - 28 June, with unsettled periods possible on 10 June. Activity is expected to increase to unsettled levels on 29 June.
