Solar Activity Report for 4/20/06
- The past 10 days have seen geomagnetic storm conditions reach the G-2
level, and some quite beautiful aurora were seen and photographed
across the northern US and Canada, as can be seen here :
http://www.spaceweather.com/aurora/gallery_01apr06_page3.htm . Yes, it
is indeed possible to have geomagnetic storms and aurora, even at the
solar minimum. Conditions are quiet at the moment, with a single,
small sunspot being visible. A loosely organized but large coronal
hole could kick up the solar wind speeds along about the 23rd.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 30
SFI : 79
A index : 4
K index : 1
Solar wind speed : 387.6 km/sec
Solar wind density : 0.5 protons/cc
Solar wind pressure : 0.1 nPa
IMF : 4.3 nT
IMF Orientation : 0.6 nT South
GOES-12 Bacckground X-ray Flux level : A3
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 at very low to low levels. Region 874
has a slight chance of producing an isolated C-class flare.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels.
A weak recurrent coronal hole may lead to isolated active periods on
