*estimated from real time data

Disturbed conditions observed on 23 and 28 Apr. The activity
on 23 Apr was due to a cme passage associated with the X1 limb
flare on 21 april from solar region 9906. This region is due to
return to the solar disk on 05 May. Flare/CME activity may
increase after this date. Milder activity on 28 Apr was
associated with a coronal hole.
2. FORECAST (02 MAY - 01 JUNE)
Disturbed Periods: 
08-09 May (mild)
24-25 may

Best Quiet Periods: 
02-07 May
14-17 May
Note: Quiet periods based on recurrence. If region 9906 returns 
and is active quiet periods may become CME disturbed.


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.
