CHANCE
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.
NOAA forecasters estimate a 40% chance of M-class
solar fares during the next 48 hours. Solar
Flare alerts: text,
phone.
MAGNIFICENT
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 could deliver a glancing blow to our planet's
magnetic field on or about September 3rd. This date
is preliminary and may be changed in response to
more data from coronagraphs on the Solar and Heliospheric
Observatory (SOHO). Stay tuned.

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
September 1, 2012 there were 1330
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.
