Solar Activity Report for 3/31/03
- ** G-1 Geomagnetic Storm In Progress **
** Aurora Watch In Effect **
As per the forecast, the solar wind speed remains elevated, and a G-1
class geomagnetic storm is in progress. Skywatchers should keep an
eye out for aurora tonight, especially in the higher latitudes. See
this link for some really beautiful aorora pictures captured over the
last several days :
. The geomagnetic storm level made it up to the G-2 (moderate)
category earlier today. The current conditions should persist for at
least the next two or three days, so look for the solar wind speed to
stay elevated throughout the period. More geomagnetic storm events
are also a likelyhood. There are numerous sunspot regions visible on
the solar disk tonight. Of the bunch, regions 319 and 33 look to have
the best flare generating potential.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 165
SFI : 160
A index : 26
K index : 4
Solar wind speed : 534.5 km/sec
Solar wind density : 2.7 protons/cc
Solar wind pressure : 1.2 nPa
IMF : 7.6 nT
IMF Orientation : 7.0 nT North
Conditions for the last 24 hours :
Space weather for the past 24 hours has been moderate. Geomagnetic
storms reaching the G2 level occurred.
Forecast for the next 24 hours :
Space weather for the next 24 hours is expected to be minor.
Geomagnetic storms reaching the G1 level are expected.
Solar activity forecast :
Solar activity is expected to be low. There is a small chance for a
low M-class flare from Region 323.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at unsettled to minor storm
levels. Disturbed periods due to high speed stream effects will
continue for the next 2-3 days.
