Solar Activity Report for 1/27/04
- ** G-1 Geomagnetic Storm In Progress **
** Aurora Watch in Effect **
Look closely at the sunspot number. You're not going to see this very
often. No, it's not a typo. Not a single sunspot is visible on the
Earth-facing side of the sun! Needless to say, solar activity is
very, very quiet. So why the geomagnetic activity? That is thanks to
a small coronal hole and a south-pointing interplanetary magnetic
field. Skywatchers in the higher latitudes should keep an eye out for
aurora tonight. On the heels of the small coronal hole is a larger
one that will soon be in an Earth-pointing position. We should start
picking up the solar wind gusts from it by the weekend.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 0
SFI : 94
A index : 15
K index : 5
Solar wind speed : 523.0 km/sec
Solar wind density : 6.0 protons/cc
Solar wind pressure : 2.0 nPa
IMF : 9.4 nT
IMF Orientation : 7.3 nT South
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 very low. There may be a gradual
increase in background and activity levels with the return of old
Region 536 (latitude S11) tomorrow (28 January).
Geomagnetic activity forecast :
The geomagnetic field is expected to be unsettled to active for the
next 24 hours (28 January) as a positive polarity coronal hole is
rotating into geoeffective position. A decline to mostly unsettled
with possible isolated active periods is expected for the second and
third days (29-30 January).
Recent significant solar flare activity :
