WARNING: Geomagnetic Sudden Impulse expected

> neither forgotten nor dropped from the list.
> The first solar flares of the new solar cycle have now begun to produce
> auroral activity. The effects of one of these flares will be arriving today
> February 8, 2010, sometime after 3pm Alaska Daylight Time (2400 UT).
> It appears to have reached the satellite ACE at 2pm AKST, (2300 UT).
> Our model shows the shock arriving at 1100 UT on the 9th, but we had to
> guess as to the initial velocity, so the 12hr time difference was not
> surprising.
> On the Auroral Forecast Website, click on the "Solar Wind" plot to see
> a movie of the shock from the sun as it spreads out to the planets. This is
> a small shock in a slow, low density solar wind so the resulting auroral
> activity will not be large, but it is good to know that the sun is awake
> again.
