MAGNETIC FROTH: Big sunspot AR1711 is not actively flaring. Instead, it is frothing. Sergio Castillo captured the phenomenon on April 2nd when he photographed the sun from Inglewood, California:

Castillo used a "Calcium K" (CaK) filter that passes light from singly-ionized calcium atoms in the sun's atmosphere. CaK filters are excellent detectors of magnetic froth--the bubbly, turbulent sea of magnetism that surrounds many large sunspot groups.

"It is amazing to see how much a calcium filter can show you," says Castillo. "Even 'quiet' sunspots look great."

How long will the quiet last? The sun has not produced a significant flare in more than two weeks. NOAA forecasters say the trend is unlikely to change today with only a slim 5% chance of M-flares and a 1% chance of X-class flares.
