The solar wind speed has been gusting up and down over the last
several days due to coronal holes coming and going. While the solar
wind speed has been close to 600 km/sec at times, no significant
geomagnetic activity has been noted. What I find most interesting at
the moment is a C-3 flare that the X-ray plot shows as being a
long-duration event. While a C-3 flare isn't close to meeting the
requirements of being a significant flare, the fact that is
long-duration makes it more likely that a CME might be launched. We
should know tomorrow if a CME has been created by this event. A
medium-sized coronal hole is squarely in an Earth-pointing position.
We'll see solar wind gusts from it within the next 72 hours.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 27
SFI : 85
A index : 5
K index : 3
Solar wind speed : 538.5 km/sec
Solar wind density : 2.4 protons/cc
Solar wind pressure : 1.2 nPa
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 to low levels. Region 824
has the capability of producing an isolated C-class flare.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to active levels
through 30 November. Minor storm conditions with a chance for isolated
high latitude major storm periods are possible on 01 and 02 December
as a recurrent coronal hole rotates into a geoeffective position.
