** G-2 Geomagnetic Storm In Progress **
** Aurora Watch In Effect **
The Earth has moved inside of a high-speed solar wind stream, and G-2
geomagnetic storm conditions prevail. An aurora watch is in effect,
and skywatchers, especially those in the higher latitudes, should keep
an eye out for aurora. The activity is expected to last about another
3 days before dying off. There is a single sunspot region visible.
I'm still watching and waiting for the one big flare that, at least
for the last few sunspot cycles, has signaled the arrival of solar
The current solar and geomagnetic conditions are :
NOAA sunspot number : 27
SFI : 82
A index : 22
K index : 6
Solar wind speed : 633.2 km/sec
Solar wind density : 4.0 protons/cc
Solar wind pressure : 2.7 nPa
IMF : 6.8 nT
IMF Orientation : 5.3 nT South
GOES-12 Background X-ray Flux level : A0
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 moderate.
Geomagnetic storms reaching the G2 level are expected.
Solar activity forecast :
Solar activity is expected to remain at very low levels.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at unsettled to active levels
though 19 and 20 March. There is a chance for isolated periods of
minor storm conditions through the geoeffective stage of the favorably
positioned coronal hole. A return to quiet to unsettled levels is
expected on 21 March as the coronal hole wanes.
