Solar Activity Report for 6/23/04
- Sunspot regions 634 and 635 are approaching the western limb of the
solar disk. While both regions are quite large and naked-eye visible
(never look directly at the sun!!), and also seem to have the magnetic
complexity to generate a significant flare, they've been quiet. The
background X-ray flux has been holding steady at B2, and about the
strongest flare we've gotten in the last few days is a C-2 event.
There is a coronal hole that has rotated into view, and it will soon
be in an Earth-pointing position. Look for some solar wind gusts from
it to arrive on or about the 29th.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 104
SFI : 113
A index : 4
K index : 2
Solar wind speed : 361.1 km/sec
Solar wind density : 4.4 protons/cc
Solar wind pressure : 0.7 nPa
IMF : 4.1 nT
IMF Orientation : 3.6 nT South
GOES-12 Background X-ray Flux level : B2
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 at low to moderate levels. Region 635
continues to exhibit the potential to produce an M-class flare.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels
through 24 June. Active conditions are expected on 25 and 26 June due
to a recurrent coronal hole high speed stream.
Recent significant solar flare activity :
