Solar Activity Report for 6/22/03
- ** Aurora Watch In Effect **
G-1 geomagnetic storm conditions are expected from time to time as the
Earth drifts though a high speed solar wind stream. See this link for
aurora that were photographed near Quebec City, Canada, Saturday night
: http://science.nasa.gov/spaceweather/aurora/gallery_01jun03.html .
This summer has been rather unusual for aurora. Typically, although
nobody understand completely why, the equinoxes seem to be much better
times for aurora watching than the solstices. However, this summer
has been the exception, as there have been numerous aurora sightings
during May and June. Sunspot region 386 has been losing a bit of its
magnetic punch and shrinking in size, and the background X-Ray flux
has been slowly dropping accordingly. However. region 386 is still
capable of producing an M-class flare. Expect the high speed solar
wind to continue for at least the next 24 hours.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 94
SFI : 110
A index : 15
K index : 3
Solar wind speed : 530.1 km/sec
Solar wind density : 2.3 protons/cc
Solar wind pressure : 1.0 nPa
IMF : 6.8 nT
IMF Orientation : 4.5 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 continue at low levels. There is a small
chance for an isolated low M-class flare from Regions 386, 387 and 388.
Geomagnetic activity forecast :
The geomagnetic field is expected to continue at unsettled to active
levels due to coronal hole high speed flow.
