/ High aurora activity
Hoping to find somewhere dark enough tonight in Fife. looks like there might be clear spells.

Looking at your link.... Do you know why quite often (/ normally ?) the aurora seems to be offset so the US gets effects a lot further south than we do?
I don't know if this is the answer to your question, but on the TV prog last night, they said the aurora circle is actually an oval that extends down into the night side of the earth (ie. away from the sun). Which, if that is correct, would mean that, about now, it extends down into the USA as it is still their nighttime.
I think it tends to be more intense and reach further South during the night time, so it'll look that way during the day here, but the opposite 12 hours later. The read arrow on the chart is the noon meridian, and tends to be where the activity is weakest.
I thought it was because the "circle" is centred on the North Magnetic Pole, which is currently around 86N 147W, rather than the North Geographic Pole.
That will be the case as it's a magnetic phenomenon but the oval extending into nighttime side of the earth seems correct, so maybe a combo of the two?
Ok i read that and kind of understood.........however can anyone tell me is there an optimum UK time? I need to know so i can decide what to tell the kids.
Around midnight local time is generally best, but of course it also depends what's actually arriving at Earth at that point.
A white glow looking north from Broadford in Skye at 1.00am. Not great though.
That makes sense
Strange. Since posting this morning the Iceland aurora forecast has gone down from 7 (strong) to 0 (quiet) for tonight.
Not here it's not... the sky seemed to have a certain brightness but that was probably due to the glow from the moon reflecting off wispy clouds. I was looking out over the Moray Firth from around Lossiemouth area, I'm now off to bed!
d'Oh. Now that I've actually clicked on your link I see that it says
"Latest Forecast = in 45 minutes, the Aurora will be Quiet"
That'll be correct then... :)
Can't help being mildly suspicious of this....don't know what others think!
I cannot place that bright star or recognise any star groups easily.
I think we are looking North then the main brightness is coming from the East, I'm not sure the Moon would be Eastern at night on Thursday, it was less than first quarter.
I smell bs
If you look at these pics...
it becomes clear that the bright star is Jupiter in the constellation of Gemini. So I'm happy about the stars now, but not sure about those auroral 'features'.
Did any of our Welsh correspondents witness these ? Surely with the smart phone ubiquity, somebody on UKC would have had a snap of them.
They have been seen a number of times in North Wales, so not impossible
The photographer said it was extremely weak to the naked eye, and only came out in the long exposures.
I think the shapes look like long exposures of clouds that have been coloured by something. Could have been by NLs, or photoshop.
The story is interesting as well... she just happened to be up there by chance and just happened to be trying a long exposure which she had "never tried before" - sounds like nonsense to me!
It's not impossible, but I'm inclined to agree. Getting the exposure just right for aurora is tricky. If you were doing exposures suitable for an LE star shot the aurora itself would be over exposed unless it was v faint.
