Solar Activity Report for 6/17/04
- The solar wind speed is a little elevated due to a coronal hole that's
in an Earth-pointing position. So far, there hasn't been much in the
way of activity, however. There are two large sunspot regions
visible, those being regions 634 and 635. They do appear to have at
least an outside chance of generating a significant flare, although so
far everything has been quiet since the M1.0 flare of the 13th.
