Solar Activity Report for 1/16/05
- What a difference a few days makes! Gone are the geomagnetic storms
and solar flares of sunspot region 720, and conditions are now just
about as quiet as they can be. There are two small sunspot regions
visible, 723 and 727, but neither appear to have the ability to
generate significant flares at this time. By the way, in case anybody
was wondering, a significant flare is a flare of M1.0 or higher.
There are a couple of coronal holes that are rotating into an
earth-pointing position, and we could start seeing high-speed solar
wind gusts from them along about the 29th.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 46
SFI : 89
A index : 3
K index : 0
Solar wind speed : 307.8 km/sec
Solar wind density : 0.4 protons/cc
Solar wind pressure : 0.1 nPa
IMF : 4.0 nT
IMF Orientation : 0.3 nT South
GOES-12 Background X-ray Flux level : A8
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 remain at very low levels.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels.
There is a chance of isolated active conditions at high latitudes on
27 and 28 January. Minor to major storming is possible on 29 January
due to the onset of a recurrent high speed coronal hole stream.
