Solar Activity Report for 8/25/03
- All is fairly quiet this evening as the Earth exist the latest high
speed solar wind stream. While the solar wind speed is still well
above 500 km/sec, the geomagnetic activity seems to have died down,
and isn't likely to fire up again for the time being. G-1 geomagnetic
storm conditions were observed within the last 24 hours. There are
four numbered sunspot regions visible. It doesn't appear that any of
them have the ability to produce a significant flare, but a low level
M-class flare isn't completely out of the question. From the extreme
UV images from the SOHO satellite, it looks like there might be a
coronal hole just beginning to peek over the eastern limb of the solar
disk, so stay tuned over the next two or three days.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 146
SFI : 117
A index : 22
K index : 3
Solar wind speed : 554.5 km/sec
Solar wind density : 1.2 protons/cc
Solar wind pressure : 0.6 nPa
IMF : 4.6 nT
IMF Orientation : 2.8 nT North
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Geomagnetic storms
reaching the G1 level occurred.
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 predominantly low for the next three
days. There is a slight chance for an isolated M-class flare.
Geomagnetic activity forecast :
The geomagnetic field is expected to be unsettled with occasional
active periods during the next two days as the current disturbance
persists. A decline to mostly unsettled is expected on the third day.
Recent significant solar flare activity :
