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 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
ones all the time.
On
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.
