I suppose this falls under the hading of taking what we can get. The
Earth entered a high speed solar wind stream a couple of days ago, and
believe it or not, there were a few sightings of aurora! See this
link for some nice pictures.
. It wasn't
much, but like I said, we'll take what we can get as were approach (or
are at?) the solar minimum. The aurora have subsided, although the
solar wind speed remains on the high side of 600 km/sec. The small
coronal that brought us the brief light show is rotating towards the
westernlimb of the solar disk, and the solar wind speed should drop
off in 48 hours or so. However, there is another small coronal hold
that will be reaching an Earth-pointing position in a few days. There
isn't anything to talk about in the way of sunspots, and I mean that
literally! The solar disk is blank yet again.
