Solar Activity Report for 5/4/04
- Just about anytime now, the Earth should be coming into a high-speed
solar wind stream coming from a coronal hole. At this moment, the
solar wind speed is slightly elevated, but that's about it. We might
see some isolated G-1 geomagnetic storm conditions on Wednesday and
Thursday, and the possibility exists for high latitude aurora. Stay
tuned. That's really about the only thing noteworthy for the time
being. There are two numbered sunspot regions visible, but neither
appear to have the potential to generate a significant flare at the
The current solar and geomagnetic conditions are :
NOAA sunspot number : 63
SFI : 87
A index : 11
K index : 2
Solar wind speed : 428.3 km/sec
Solar wind density : 6.3 protons/cc
Solar wind pressure : 1.3 nPa
IMF : 8.7 nT
IMF Orientation : 8.3 nT North
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 atcivity forecast :
Solar activity is expected to be very low to low. Region 601 may
produce C-class flares.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to active with isolated
minor storm conditions on days one and two (5-6 May) as a coronal hole
high speed wind stream moves into geoeffective position. Activity
should subside to quiet to unsettled levels on day three (7 May).
Recent significant solar flare activity :
