** Aurora Watch In Effect **
While geomagnetic activity hasn't necessarily been anything to do
handsprings over, there have been G-1 geomagnetic storm conditions
within the last 24 hours, and that is expected to continue for at
least the next 24 hours. The Earth has drifted into a high speed
solar wind stream coming from a coronal hole, although the solar wind
speed hasn't been particularly high this time around. It's mainly
been in and around the 500 km/sec mark, although it is a little lower
than that at this moment. There is at least a chance for some aurora
tonight, especially in the higher latitudes of the northern US,
Canada, and northern Europe. Two new sunspot regions are just now
rotating into view, so expect to see the sunspot number rise a bit
over the next few days. However, the background X-ray flux is holding
low and steady, which is a good indicator that we shouldn't expect to
see anything in the way of significant flares for the time being.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 87
SFI : 118
A index : 15
K index : 3
Solar wind speed : 443.9 km/sec
Solar wind density : 5.5 protons/cc
Solar wind pressure : 1.8 nPa
IMF : 7.6 nT
IMF Orientation : 3.7 nT South
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 :
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 362
has the potential for C-class activity.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to active levels.
Coronal hole high speed stream effects are expected to continue
through day one of the period with active conditions possible. Quiet
to unsettled conditions are expected on day two and day three.
