Solar Activity Report for 2/12/05
- View SourceIt's a quiet weekend as the Earth is exiting a high-speed coronal hole
solar wind stream. There are five sunspot regions visible, but none
of them look to have the potential of generating a significant flare
at the present time. A small coronal hole has appeared over the
eastern limb of the solar disk, and it we could begin to see some
solar wind gusts from along about the 18th.
