Solar Activity Report for 2/22/05
- There hasn't been any more significant flare activity since the single
M3.3 outburst from sunspot region 735. In fact, the two visible
numbered sunspot regions are on the verge of rotating over the western
limb of the solar disk. Look for the sunspot number to drop even
lower than it is if nothing else comes into view. There is a rather
large coronal hole that has rotated into an Earth-pointing position.
We should see some high speed solar wind gusts from it about the end
of the week.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 23
SFI : 92
A index : 6
K index : 1
Solar wind speed : 351.0 km/sec
Solar wind density : 0.6 protons/cc
Solar wind pressure : 0.2 nPa
IMF : 9.8 nT
IMF Orientation : 5.5 nT North
GOES-12 Background X-ray Flux level : B1
Conditions for the last 24 hours :
No space weather storms were observed for the past 24 hours.
Forecast for the next 24 hours
No space weather storms are expected for the next 24 hours.
Solar activity forecast :
Solar activity is expected to be at very low levels throughout the period.
Geomagnetic acctivity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels
through 23 February. A recurrent high speed coronal hole stream should
become geoeffective on 24 February. Active conditions are possible on
24 and 25 February due to the coronal hole influences.
