Solar Activity Report for 12/13/03
- View Source** Aurora Watch In Effect **
The Earth remains inside of the high speed solar wind stream tonight,
and more geomagnetic storm conditions have been observed. The aurora
watch is still in effect. Starting tomorrow, the solar wind speed
should start backing off from its current level, and we'll see an
accompanying decline in the degree of geomagnetic activity. However,
don't be surprised if there are some G-1 geomagnetic storm conditions
observed from time to time for the next 24 hours. Currently, there
are two numbered sunspot regions visible. Neither looks to have the
potential for generating a significant flare at the present time.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 40
SFI : 88
A index : 27
K index : 4
Solar wind speed : 744.3 km/sec
Solar wind density : 0.6 protons/cc
Solar wind pressure : 0.7
IMF : 6.0 nT
IMF Orientation : 3.1 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 :
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 very low to low.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at unsettled to active levels
for 14-15 Dec. Quiet to unsettled conditions are expected on 16 Dec.
