For the past few days, the Earth has been inside of a high speed solar
wind stream coming from a coronal hole, although you might not have
not have noticed anything. Although the solar wind speed did kick up
into the high 500's, there was little, if any, geomagnetic effect.
The solar wind speed is decreasing now, so it is unlikely that we will
see any effects from this event. I don't see anything noteworthy in
the way of sunspots or coronal holes right now, so I would expect the
next several days to be quiet.
