Things have been pretty quiet since my last report. There were a
couple of coronal hole encounters, but neither stirred things up very
much. At present, there is a single sunspot region visible. That
sunspot region is getting a little interesting. It is growing
rapidly in size, and is developing magnetic compexity. We'll see if
the magnetic field lines become entangles enough to start producing
significant flares. There's also a small coronal hole rotating into
an Earth-pointing position. Look for the solar wind gusts to arrive
on or about the 24th.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 28
SFI : 94
A index : 4
K index : 0
Solar wind speed : 386.2 km/sec
Solar wind density : 0.8 protons/cc
Solar wind pressure : 0.2 nPa
IMF : 3.5 nT
IMF Orientation : 1.6 nT South
GOES-12 Background X-ray Flux level : A9
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 low. The increased magnetic
complexity in Region 848 will likely result in C-class activity.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled on 22
January. Occasional active periods are possible on 23 and 24 January
as a coronal hole high speed stream rotates into geoeffective position.
Recent significant solar flare activity :
