Aurura alerts seem only to be based on whether there is an ongoing
geomagnetic
storm; By the time I see it, it's often too late. Why does someone not
issue
an alert two days beforehand when there is such a flare?


Sign up for alerts here

My Aurorawatch email (to which I am already signed up) arrived in the last
5 minutes. I may have missed the best of it by now (it's cloudy
anyway...).
Aurorawatch only alerts when a storm is taking place.

I assume that I need to sign up to the flare alert. But the last archived
message to that list was on 15th January, so it wasn't a very good
predictor.


The AstroAlert attempts to predict arival times and probablity of Aurorae
but admitedly was late with this one (Alert arrived 19:29 this evening
predicting Aurora for tonight and/or tomorrow)

Geomagnetic activity is the only really reliable indicator. Fairly
often there will be a flare but no aurora even with earth directed
flare. I look at http://www.spaceweather.com at least once a day, that
announces flares and the chances of aurora activity. Gives me a 24 to
48hrs notice.

They do an alert service but I thought that was a geomagnetic based
one. I assume you are already aware of the York Magnetometer alert
service and ADEC from http://www.aurorachasers.com

Hi there Gang,

good view of auroral display from Huddersfield last night.
Started off at around 9.45pm with a curtain of greenish glow
rising up from the northern horizon (above the sky glow
from Huddersfield).
Over a period of about 30+minutes it developed (at least) two light
pillars and was topped off by a rim of pink/orange glow.

I only had the opportunity to take some crude photo's using a Nikon CoolPix
5200.

The best of the bunch is on my Society's webpage -
www.huddersfieldastronomy.org
and I've posted an image to the QCUIAG website as well.
You can just make out a 'green' pillar of light - NB exposure was only ~4
seconds -
the limit of the camera.

regards

Robert

I don't get that far. It fails at the DNS lookup stage not 404 - Page

Cheers Guys,

the link is/should be www.huddersfieldastronomy.org.uk

There's quite a few other images that myself and others have taken,
from various locations, in the past years.

I know the aurora picture is a bit faint but at least I've got it on record
now.

regards

Hello again gang,

I've now had chance to spend some more time processing the
raw digital camera image of the Aurora from Huddersfield.

This has increased the filesize to ~ 1 MB, but it DOES
show a lot more detail than the thumbnail I originally
placed on the HAPS website.

If anyone would like a look (and has broadband) drop
me an e-mail at .

regards

Robert

Only just back from hols. Just before 10pm on Friday 21st we spotted
very bright green curtains from Marchmont in Edinburgh, visible through
streetlights and the wash from a nearly full Moon. Certainly the
brightest I've ever seen it from here. We headed for the Meadows and
spotted a partial corona overhead and some white pillars from there to
the north. The north sky not covered by green curtains had a strong
green tint. To the east and west, as well as near the Moon which was
20 degrees south of overhead, there was a red wash effect, the first
time I've ever seen reds from Edinburgh. Over the next half hour it
faded away completely and looking out occasionally until about 4am I
didn't see any other activity.
