Solar Activity Report for 3/29/07
- View SourceThis past weekend saw some brief G-1 geomagnetic storm activity as the
Earth moved through a high-speed coronal hole solar wind stream,
although there were no reports of aurora. There is but a single small
sunspot region visible. The sunspot cycle seems to be progressing as
expected towards the expected minimum, which should come in early
2006. There is a coronal hole coming into view, and we should begin
to see some high-speed solar wind stream effects along about April 4th.
