Solar Activity Report for 1/29/03
- All is relatively quiet this evening as we await the arrival of the
next set of coronal hole solar wind gusts, which should be arriving
sometime tomorrow. For the time being, however, the solar wind speed
has settled into the 450 km/sec range. The current K index, oddly
enough, is 4, which indicates an active geomagnetic field. Minor
storm level is 5. The aurora monitors show that there might be some
aurora visible in the higher latitudes, so take a peek at the sky if
you're out around local midnight or after. There isn't much happening
on the sunspot or flare front for the present time. None of the six
sunspot regions visible currently look as if they have any flare
generating potential, although sunspot region 274, which has just
rotated into view, isn't in a position yet to get a decent look at it.
The relatively large disparity between the low SFI and the higher
sunspot number indicates that none of the sunspots currently visible
are very energetic.
