Solar Activity Report for 8/7/02
- View SourceThe coronal hole effects persist this evening, but so far there hasn't
been any geomagnetic activity to speak of. Sunspot region 57, which
is right at the western limb of the solar disk, delivered a parting
shot today in the form of an M-1 flare. Sunspot regions 61 and 63
have the potential for generating more M-class flares. The coronal
hole solar wind stream should stay in place for several more days, as
there is another cononal hole that is in position right behind the one
that has recently passed.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 141
SFI : 136
A index : 7
K index : 1
Solar wind speed : 308.0 km/sec
Solar wind density : 6.1 protons/cc
Solar wind pressure : 0.9 nPa
IMF : 5.7 nT
IMF Orientation : 5.0 nT North
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 fair
chance for an isolated M-class event sometime during the next three
days. The most likely sources for flare activity are Regions 57, 61,
Geomagnetic activity forecast :
The geomagnetic field is expected to be mostly unsettled with a slight
chance for active levels during the next 24 hours. Enhanced activity
may occur in response to a favorably positioned coronal hole.
Conditions are expected to be unsettled on day two and quiet to
unsettled on the third day.
