COMMENT: The ACE spacecraft recorded a shock in the solar wind at 05h00 UT,
this morning. The solar wind speed increased from -an already very high value-
of 775 km/s to more than 900 km/s and the density jumped up by an order of
magnitude. This might mark the end of the coronal hole influence we have
experienced in the last days. Yet, given the very high solar wind speed and the
presence of yet another coronal hole, we expect continued geomagnetic activity
at the minor storm level.
