2463Solar Activity Report for 7/02/05
- Jul 2, 2005** Aurora Watch In Effect **
The Earth is in a high speed solar wind stream coming from a coronal
hole, although so far, there hasn't been much in the way of
geomagnetic activity in response to it. Nevertheless, an aurora watch
is in effect, and skywatchers in the higher latitudes should keep an
eye out for aurora. After being completely devoid of sunspots not
long ago, the sun is now peppered with seven numbered sunspot regions.
Of the group, sunspot regions 782 and 783 are the largest, and are
growing in size. Neither of them appear to have the magnetic
complexity to generate a significant flare, but stay tuned. That
The current solar and geomagnetic conditions are :
NOAA sunspot number : 168
SFI : 124
A index : 16
K index : 4
Solar wind speed : 537.3 km/sec
Solar wind density : 3.8 protons/cc
Solar wind pressure : 1.2 nPa
IMF : 4.2 nT
IMF Orientation : 3.2 nT North
GOES-12 Background X-ray Flux level : B3
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 mostly low, but there is a chance for
an isolated M-class during the next three days (3-5 July). Of the
eight spotted regions on the disk, 785 and 783 appear to be the most
likely sources for future M-class level activity.
Geomagnetic activity forecast :
The geomagnetic field is expected to be predominantly unsettled, but
there is a continued chance for occasional active periods during the
next two days (03-04 July) as effects from the coronal hole are
expected to linger. Conditions should decline to mostly quiet by the
third day (05 July).
Recent significant solar flare activity :
