Solar Activity Report for 4/30/02
- The Earth remains inside a coronal hole generated high speed solar
wind stream this evening, as it has been in for the last 3 days. The
solar wind speed and density has remained elevated, although it has
not caused much in the way of geomagnetic activity. None of the
relatively few sunspot regions visible this evening look like they
have much in the way of flare generating potential, although there was
a modest M-class flare earlier today.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 113
SFI : 153
A index : 8
K index : 2
Solar wind speed : 409.3 km/sec
Solar wind density : 5.6 protons/cc
Solar wind pressure : 1.3 nPa
IMF : 7.9 nT
IMF Orientation : 3.6 nT North
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Radio blackouts
reaching the R1 level occurred.
Forecast for the next 24 hours :
Space weather for the next 24 hours is expected to be minor. Radio
blackouts reaching the R1 level are expected.
Solar activity forecast :
Solar activity is expected to be low to moderate. A general trend of
increased activity is expected as the east limb regions rotate onto
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled.
