Solar Activity Report for 8/2/03
- ** Aurora Watch In Effect **
It's no secret that the Earth has been inside of a high speed solar
wind stream for about a week now. The result has been some beautiful
aorora displays seen over the last several nights in several locations
in the northern US and Canada, as can be seen here :
The Earth now exiting the stream, and the solar wind speed is slowly
dropping from the near-800 km/sec level it was at for the last couple
of days. The speed remains elevated, however, and there's still a
chance of some more aurora tonight. There's also been a bit of flare
activity, with an M-1 class flare coming late on the 2nd. The solar
wind speed should steadily decline over the next three days, but it
may not last for long. There's another coronal hole that's rotating
into position, and we could see some effects from it around the middle
of the week. Stay tuned!
The current solar and geomagnetic conditions are :
NOAA sunspot number : 95
SFI : 111
A index : 24
K index : 3
Solar wind speed : 658.1 km/sec
Solar wind density : 1.1 protons/cc
Solar wind pressure : 0.7 nPa
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 :
No space weather storms are expected for the next 24 hours.
Solar activity forecast :
Solar activity is expected to remain low. Region 424 (S18E64)
continues to pose the greatest threat with only a slight chance for
M-class x-ray flare activity.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at unsettled to active levels.
The coronal hole is in the process of moving out of geoeffective
range, and no recurrent solar features should impact earth for the
next three days.
