Solar weather map

Fe XV 284 Å EIT image with NOAA regions (red) and Catania sunspot groups (green). The arrows point from the observed location to the probably location corresponding to the background map (taking into account the solar rotation and the different times of observation). Click on the image to see an enlarged version.

Catania Sunspot group 41 (NOAA AR 9484), covers about the same area as one planet Earth and has a beta-gamma magnetic configuration that could trigger M-class solar flares. Any eruptions from this Sun-centered spot would likely be Earth directed.
