** G-1 Geomagnetic Storm In Progress **
** Aurora Watch In Effect **
The Earth has moved inside of a high-speed solar wind stream coming
from a coronal hole. G-2 geomagnetic storm condition have been
observed within the last 24 hours, and G-1 geomagnetic storm is in
progress. No aurora sightings have been reported yet, but my guess is
there will be. G-1 geomagnetic storm conditions are expected to
persist over the next 24 - 48 hours, with the activity level dropping
off on the 14th. Only one sunspot region is visible on the solar disk
tonight, and it doesn't look to have the potential to generate any
The current solar and geomagnetic conditions are :
NOAA suspot number : 17
SFI : 88
A index : 8
K index : 5
Solar wind speed : 511.1 km/sec
Solar wind density : 9.4 protons/cc
Solar wind pressure : 3.4 nPa
IMF : 8.3 nT
IMF Orientation : 0.6 nT North
GOES-12 Background X-ray Flux level : A9
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 for the next three
days (12-14 April).
Geomagnetic acctivity forecast :
The geomagnetic field is expected to be mostly active for the next two
days (12-13 April) as the high speed stream from the coronal hole
should continue to drive activity. There is a chance for isolated
minor storm periods during this time as well. Conditions are expected
to subside to unsettled with occasional active periods for the third
day (14 April).
