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.

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."

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.
Notes: LD means
"Lunar Distance." 1 LD = 384,401 km, the distance
between Earth and the Moon. 1 LD also equals 0.00256
AU. MAG is the visual magnitude of the asteroid on
the date of closest approach.
