OF FLARES: Sunspot AR1560 has more
than quadrupled in size since August 30th, and now
the fast growing active region is directly facing
our planet: movie.

ERUPTION: A filament of magnetism
curling around the sun's southeastern limb erupted
on August 31st, producing a coronal mass ejection
(CME), a C8-class
solar flare, and one of the most beautiful movies
ever recorded by NASA's Solar Dynamics Observatory:
The explosion hurled a CME away from
the sun traveling faster than 500 km/s (1.1 million
mph). The cloud, shown
here, is not heading directly toward Earth,
but it will deliver a glancing blow to our planet's
magnetic field. NOAA forecasters estimate
a 40% chance of strong polar geomagnetic storms
when the cloud arrives on Sept. 3rd.

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
all the time.
September 2, 2012 there were
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.
