** Aurora Watch In Effect **
The high speed solar wind flow continues tonight, and was up over the
700 km/sec earlier today. There were G-2 geomagnetic storm conditions
observed within the last 24 hours. While the solar wind speed has
dropped of some, aurora are still a definite possibility tonight, and
skywatchers in the higher latitudes should keep an eye to the sky.
The activity should continue for about the next 24 hours, but then
drop off as the solar wind speed declines. There is but a single
numbered sunspot region visible on the solar disk, although it looks
like there are more getting ready to rotate into view, and the
background X-ray flux has increased during the last 24 hours.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 37
SFI : 101
A index : 26
K index : 2
Solar wind speed : 619.1 km/sec
Solar wind density : 3.6 protons/cc
Solar wind pressure : 2.4 nPa
IMF : 7.3 nT
IMF Orientation : 0.4 nT North
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 very low to low. The background
levels are likely to continue to increase slightly with the addition
of regions which are now visible in GOES Solar x-ray imagery behind
East limb at N20 and S25.
Geomagnetic activity forecast :
The geomagnetic field is expected to be mostly active but decreasing
to unsettled within the next 24 hours as the current disturbance
transitions out of geoeffective range. Continued unsettled levels are
expected for days two and three.
Recent significant solar flare activity :
