SLIGHT CHANCE OF FLARES: New sunspot AR1682 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares. NOAA forecasters estimate a 10% chance of an eruption. Solar flare alerts: text, voice.

FARSIDE CME: There is an active sunspot on the farside of the sun. Yesterday, Feb. 25th, it blasted a coronal mass ejection (CME) over the sun's northwestern limb, shown here in a movie from the Solar and Heliospheric Observatory:

A 3D model of the CME prepared by analysts at the Goddard Space Weather Lab shows that the CME will miss everything--no planets are in the line of fire.

NASA's STEREO-Ahead spacecraft is stationed over the farside of the sun, almost directly above the CME. Images from the spacecraft pinpointed the source of the blast: It is active sunspot AR1678, which rotated off the Earthside of the sun just a few days ago.

SNOW MOON: According to folklore, last night's full Moon was the "Snow Moon," so-called to mark the heavy snows of February. Göran Strand of Östersund, Sweden, photographed the moonrise and wrapped his images into a 360-degree self-portrait of snowy moon-watching:

"To visualize the Snow Moon, a friend and I decided to go for a walk out on a big lake, covered with snow, so that I could create a snowy planet matching the snowy moon," says Strand. "As we stood there watching the moon, a mist blew in from the south, adding some 'atmosphere' to the composition."

More moonshots from last night may be found in the realtime gallery:

  Near Earth Asteroids
Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
On February 26, 2013 there were 1381 potentially hazardous asteroids.
