Today's magnetic observation...



Today's image is a magnetic map of the sun. Two active regions are circled. Their polarity identifies them as members of new Solar Cycle 24, but they lack the dark cores required of true sunspots. So, in spite of these lively magnetic imprints, we must still say "the sun is blank--no sunspots." Credit: SOHO/MDI
