STORM WARNING: A pair of CMEs is heading for Earth. The two solar storm clouds were launched on Sept. 9th and 10th by strong explosions in the magnetic canopy of sunspot AR2158. NOAA forecasters estimate a nearly 80% chance of polar geomagnetic storms on Sept. 12th when the first of the two CMEs arrives. Auroras are in the offing, possibly visible at mid-latitudes before the weekend..

EARTH-DIRECTED X-FLARE AND CME: Sunspot AR2158 erupted on Sept. 10th at 17:46 UT, producing an X1.6-class solar flare. A flash of ultraviolet radiation from the explosion ionized the upper layers of Earth's atmosphere, disturbing HF radio communications for more than an hour. More importantly, the explosion hurled a CME directly toward Earth.

If I can find somewhere in the country that doesn't have cloud I'll try and take a photo...
 
So when they say mid-latitudes, what are they talking about, in terms of what countries they'll be visible from?

Roughly anywhere between the tropical zone in red and the Arctic/Antarctic circles on the map below, although there are a lot more factors involved and steps you should take to determine whether or not you'll be able to see an aurora.



If you look around, you should also be able to find aurora alerts tailored to your location, and some will even send you emails or texts for a small fee.

Knowing our recent luck with the weather, I'm sure we'll be clouded out again. Otherwise, I'd likely have some pretty good luck as I have in the past with auroras.
 
I was out last night. Clearish night but lots of coastal fog in my usual night sky viewing spot, plus a very bright moon.

Solar activity was low, however. It didn't start picking up until later in the morning. Tonight might be a better night, but we'll see what the old Kp-index-ometer says closer to midnight.
 
Well, clouded out last night, just like I predicted. This has been our same tune now for well over a year whenever some astronomical event happens. We nearly got fully clouded out during the Transit of Venus a couple of years ago, but got. a narrow viewing window thanks to a hole in the cloud cover
 
Have seen a few great shots from western Canada and from Maine and Oregon from the US. NZ got covered by cloud plus the CME impacts were during our daylight hours so we didn't see much of anything.

Got a few good milky way shots so not all lost.
