Aurora Alert

Aurora Alert was created by galwayskywatchers
AURORA ALERT: A geomagnetic storm is in progress. The cause: a solar wind stream is buffeting Earth's magnetic field. Auroras have been sighted in several northern US states, Earth is inside a solar wind stream flowing from a coronal hole, giant Sunspot 923 is big but strangely quiet.

There is some person on these boards with a huge amount of bad luck trailing behind them. Whenever a significant event pops up from view in Ireland, the weather is always bad...


...Me? I blame Albert! He always wants it to be cloudy to show off light pollution!

X-FLARE: Sunspot 930 has just unleashed another big solar flare, an X3-class explosion at 0240 UT on Dec. 13th. Auroras possible, unlikely to be seen though..as usual.

Further to this, it has caught the attention of cnn.com...

Solar storm headed for Earth
Space weather forecasters revised their predictions for storminess after a major flare erupted on the sun overnight threatening damage to communication systems and power grids while offering up the wonder of Northern Lights.

"We're looking for very strong, severe geomagnetic storming" to begin probably around mid-day Thursday, Joe Kunches, Lead Forecaster at the NOAA Space Environment Center, told SPACE.com this afternoon.

The storm is expected to generate aurora or Northern Lights, as far south as the northern United States Thursday night. Astronauts aboard the international space station are not expected to be put at additional risk, Kunches said.

Radio communications, satellites and power grids could face potential interruptions or damage, however.

But what's the point... it's still raining out there!

Checked for solar storms and surprisingly found these, the one featured below is interesting though advertising for "Starry night" software

Nice X class flare again today www.n3kl.org/sun/images/noaa_xrays.gif ?
K index is around 6 (depends where you check)
www.dk0wcy.de/magneto/magnet.htm this one in Germany shows activity rising sharply but BZ index is positive, Mid latitude aurora warning but no radio aurora on vhf here

Does this mean that if it was clear, there would be no visible aurora ??

Another X class flare just now guys/girls (2nd one today)
Dave as far as I see it, unless the BZ index is very mush minus we never get visual aurorae down at these latitudes, there is no sign of activity here yet, seems unlikely either tonight, very often ham radio people (myself included) spot contacts via aurora here on this activity cluster under either 144 or 50mhz "CUSTOM SPOTS"

Next 36 hours may be interesting

All that kind of went over my head, but a loose translation I believe is that there is strong geomagnetic activity over Ireland in the radio band. Due to bad weather for visual observations, radio frequencies are confirming activity as Charles spoke!

Just deleted my comments re CNN as u had it covered already Seanie.
VHF radio aurora being reported right now as far south as Holland, looks good for here later, Kiruna dipped to -2200!!! last night, I don't ever remember seeing it that low b4, BZ index is minus right now, only thing is the weather is even worse than last night..... :-(
Seanie, we will have to get u a ham radio licence :-) morse included

An aurora observing tutorial with scanners would go down well at a starparty I'd imagine :-)
