Solar Activity Report for 5/9/04
- The Earth is exiting a coronal hole solar wind stream, and the solar
wind speed has dropped down to the 400 km/sec range. With no
substantial coronal holes in view and no sunspots that appear to have
the ability for producing a significant flare, things should be pretty
quiet for the forseeable future. There are two new sunspot regions
that have just rotated into view. Time will tell if they develop into
