All

There is a Aurora alert out at the moment. So keep a look out.

Have a look at this site, http://www.spacew.com/plots.php

Please report if you see any Aurora.

Good luck.

I can't understand those graphs.

In normal mans talk, where should we look? South? Straight up?

Dave47tuc (David) · #3 05-04-2005, 09:06 PM

I don't go much on the graphs either

Look south my friend. You never know. I looked before nothing.

ballaratdragons (Ken) · #4 05-04-2005, 09:14 PM

Thanks Dave. I'll be out there soon. Just letting the scope cool down naturally without the fan. I will report anything. I don't think our northern friends have much sky tonight according to weather report. Sky is 10/10 here.

Mick (Michael) · #5 05-04-2005, 09:25 PM

I'd love to see one someday; it would be an unusual sight in Nth Qld.

Robby · #6 05-04-2005, 09:27 PM

Nothing here in NZ tonight. Well not from 39°S anyway.
I would think tomorrow night we would more likely see some action...
Keep looking up!

Here you go Mick.. One from November last year.http://www.2fdesign.co.nz/astronomy/Aurora/Aurora11.jpg
Cheers

Cheers for the heads-up. Spaceweather is supposed to email me when this happens, but the alert seems to have gone missing this time.

Unfortunately its 100% cloud cover here tonight anyway.

I've got a few pics from last Novembers show too (what a night that was!), you can see them here if interested:

Great shots Vermin... Your just a bit further South than I, you lucky bugger!

rowena · #10 05-04-2005, 10:06 PM

this is the australian government website that monitors radio and space services, including aurora's and the suns flares.

http://www.ips.gov.au/

and the url for the space weather..

http://www.ips.gov.au/Main.php?CatID=2

no current alert for australia for aurora's but there is geomagnetic warning for the sun.

you can also report aurora's at this website and look at other reports.

Mick (Michael) · #11 05-04-2005, 10:09 PM

Are the colours like that to the eye? very cool photos Robby and Vermin thanks.

Robby · #12 05-04-2005, 10:14 PM

No you don't see that sort of colour with the eye. You do see colour however, albiet faintly.
Cheers

ballaratdragons (Ken) · #13 05-04-2005, 10:18 PM

Yes Mick, they look that good by eye!

Tom, what was the address of that Aurora site you gave last time. I was able to understand that one.

Vermin (Tom) · #14 05-04-2005, 10:37 PM

This one Ken?

As to colour, earlier on in the night I could see my shadow by the aurora, colour was mostly yellow-green, the purple/red was not seen.

Later on in the night the reds were definitely visible towards the zenith.

STD Aurora Monitor shareware is worthwhile downloading if you want to keep an eye on all the info:

http://www.spacew.com/aurora/

The POES South plot and Costello KP index, are the ones to watch for current events. The GOES proton flux and Solar X-rays are good plots for determining what is headed our way.

ballaratdragons (Ken) · #16 05-04-2005, 10:45 PM

No Tom, that's not it. The one I mean had real-time sattelite imagery of the Aurora over the suface of the globe.

EDIT: I found it Tom. I did a site search and found your old post. Thanks. http://www.sec.noaa.gov/pmap/

Vermin (Tom) · #17 05-04-2005, 10:55 PM

That sounds like the POES plots.

http://www.sec.noaa.gov/pmap/

Note that they are actually predicted auroral visibility levels based on proton flux density from one pass of a polar orbiting satellite, they are not actually satellite photos. See this for info:

http://www.sec.noaa.gov/pmap/Intro.html
http://www.sec.noaa.gov/pmap/html/200504051034S16.html

These are real images (far ultra violet), but are not updated as frequently:

http://sprg.ssl.berkeley.edu/image/latest_wic.html

STD am will download all these images for you automatically. It's a bit of a heavy data load for a dial-up connection though.

ballaratdragons (Ken) · #18 05-04-2005, 11:03 PM

Thanks Tom,

That berkley one is very good.

iceman (Mike) · #19 06-04-2005, 06:01 AM

Awesome shots Robby and Tom.

Vermin (Tom) · #20 27-05-2005, 03:07 PM

Another (mild) alert for this coming weekend for those in high latitudes:
