Solar Activity Report for 3/14/04
- View Source** G-1 Geomagnetic Storm In Progress **
** Aurora Watch In Effect **
Although the Earth is leaving a high speed solar wind stream and the
solar wind speed is declining, G-1 geomagnetic storm conditions are
being observed as I write this, and an aurora watch remains in effect
for tonight. This event produced aurora what were seen and
photographed at a number of locations across northern Europe, Canada,
and the northern US. See this link for some impressive aurora
Tonight's geomagnetic storm should be the last hurrah, and I expect to
see conditions return to normal tomorrow. Sunspot region 570, once a
large sunspot region, actually split in half over the weekend. It has
lost some of its magnetic complexity, but still has at least an
outside chance of producing a significant flare.
