*estimated from real time data

Active to minor strom conditions were observed on the 27 and
28 of March due to the arrival of CME associated with flare
activity observed on the 24 and 25 March. Severe storm conditions
were also observed on the 31 March following the arrival of a
strong shock at 0051 UT. Active to unsettled conditions followed
over the 1 and 2 of April due to sustained high solar wind speed.
A further shock was observed on the 4th of April triggering active
to minor storm conditions.

2. FORECAST (05 APRIL - 05 MAY)
Disturbed Periods: 
05-12 April, flare/CME geomagnetic activity expected from region 9415
17-21 April, coronal holes
23-29 April, returning active region

Best Quiet Periods: 
13-16

PEASE NOTE:  
At this time of the solar cycle, space weather conditions 
are frequently determined by short timescale events, not 
able to be forecasted a week in advance.
