They came from outer space--and you can have one! Genuine meteorites are now on sale in the Space Weather Store.
RADIO BURSTS: This week's sharp
increase in solar activity has turned the sun into
a radio transmitter. Bursts of shortwave static
are coming from the unstable magnetic canopy of
sunspot 1283. Tuesday in New Mexico, amateur radio
astronomer Thomas Ashcraft recorded some samples
at 21 MHz: listen.
Radio listeners should remain alert for this
kind of solar activity as sunspot 1283 continues
FLARE ACTIVITY CONTINUES: On Sept.
8th at 1546 UT, sunspot 1283 unleashed an M6-class
solar flare. This continues the active region's
3-day trend of daily powerful eruptions. Yesterday's
blast, an X1.8-class
event, produced a bright flash of extreme UV radiation
and hurled an inky-dark plume of plasma into space.

Since Sept. 6th, sunspot 1283 has
propelled at least three CMEs in the general direction
of Earth. Glancing blows from the incoming clouds
will commence sometime on Sept. 9th and continue
through Sept. 11th, possibly sparking minor geomagnetic
storms. Solar flare
X-flares of Solar Cycle 24:
There have been only a handful of X-flares since
the beginning of new Solar Cycle 24. Here is a complete
list so far, all in 2011: Feb. 15 (X2), March 9
(X1), Aug. 9 (X7), Sept. 6 (X2), Sept. 7 (X2). Before
these five, the previous X-flare occured on Dec.14,
2006, (X1) during old Solar Cycle 23.
SEASON: September is only one week
old and it has already been a good month for Northern
Lights. With the midnight sun doing a late-summer
fade, many Arctic sky watchers are seeing auroras
for the first time in months. Sylvain Serre of Ivujivik,
Canada, photographed this satisfied observer on
"For the first time this season, we had clear
dark skies in the village of Ivujivik in northern
Quebec," says Serre. "The Northern Lights
were very bright, dense and colorful."
As shown in the
gallery, similar displays have been observed
almost every night this month. More auroras are
possible on September 9th -11th in response to the
expected arrival of three CMEs propelled in our
direction by sunspot 1283. Stay tuned. Aurora
