Vento solar ejetado por buraco no Sol provoca auroras mais fracas que o esperado
Even though the gust of solar wind that has been promised for a few days hasn't appeared, tonight's #aurora prediction looks stronger than I would have expected.
A LARGE HOLE IN THE SUN'S ATMOSPHERE: Geomagnetic storms are possible on Dec. 4th and 5th when a solar wind stream is expected to hit Earth's magnetic field. The gaseous material flows from a massive hole in the sun's atmosphere. What does this mean for Earth? More lower latitude aurora? https://spaceweather.com has the latest.

"Bid me discourse, I will enchant thine ear,
Or, like a fairy, trip upon the green,
Or, like a nymph, with long dishevell'd hair,
Dance on the sands, and yet no footing seen:
Love is a spirit all compact of fire,
Not gross to sink, but light, and will aspire."

Are fou able to use #aurora ? I got a "server down for maintenance" for 2 days already ...
At last I've got a photo of the Aurora!
This is from last night, too faint to actually see (hopefully better performances in the coming days) but a long exposure did the trick. I've processed the colours (lightness) so they stand out a bit more, subtracted a dark frame, used a hot pixel filter to clean it up. Otherwise, that's it.
18mm, 32sec exposure, f3.5, ISO 400.
You can see the trails of two aircraft if you look closely.

The geomagnetic storm is over & the #aurora has returned to a low intensity phenomenon.
Here's a timelapse taken through my fisheye lens (an 8mm f/4.0 lens) between 00:20 and 01:53 on Sunday 2nd December. It is comprised of 95 images initally of 30 seconds but eventually reducing to 14 seconds. This isn't particularly beautiful but it does show the scale of the display and a SAR arc quite nicely despite the clouds. I love circular fisheye images as they give a much nicer representation of the "dome of the sky" rather than panoramas in my opinion! #aurora #NewZealand
Ooh. Aurora Watch UK has just issued a red alert, suggesting Aurora Borealis may be visible from all parts of the UK - meaning parts of Ireland may be able to view them too. 😀

This is Steve. (I refuse to call it STEVE; that’s a forced backronym. They called it Steve as a placeholder, because nobody knew what it was or what caused it, and the name stuck. It’s Steve. Not STEVE. Hi, Steve.)
Steve is a flow of charged particles that shows up as a narrow purple band, often accompanied by green “picket fence” spots. It’s not new, but it wasn’t realized that it was not just an ordinary auroral phenomenon, but had a separate mechanism.

Speaking of CMEs (Coronal Mass Ejections, when a big blob of charged crap explodes off the Sun—CMEs affect Earth when they hit us, causing aurora, radio interference, etc), I’ve only seen the aurora once. I went to college at about 45°N latitude, and once we got lucky; a geomagnetic storm caused by a CME produced a visible aurora. Not the most spectacular—a pulsing but diffuse green glow over much of the sky.
I’ve never seen Steve.
01/12/2023 - Welcome to Meteorological winter. What a cold day to start December. We headed out for a walk up the hill just after sunset. Took tea with us. It was a chilly sit but wrapped up and little wind, felt OK. Nice to relax, have our butties and watch the night sky slowly, very slowly turn. On the way back we noticed a faint hint of aurora to the north. We stood and watched for a bit as we finished our flask of coffee. Cold now, round -3, time to go home.
"De-orbiting #SpaceX #rockets are smashing temporary holes in the upper #atmosphere, creating bright blobs of light in the sky. Now, scientists have warned that these 'SpaceX auroras,' which look like glowing red orbs of light, could be causing unrecognized problems — though they are not a threat to the #environment or life on #Earth."
@edavies You're not relevant, or weren't for this forecast as it was about freezing temperatures over central and southern Scotland . . . With regards to the Aurora, at the moment there's no significant activity, but we all know how quickly that can change
Meanwhile here's a few photos I took last weekend
We are currently at planetary K-index Kp = 7!
Looks like the CME arrived at earth a little later that previously predicted.
Hopefully those in the western part of N America and in the Pacific can get to see some bright auroras.
It is predicted to peak again at Kp = 6.67 later today between 21:00 and 00:00 UTC.
NOAA SWPC has updated the CME predictions to include no less than four CMEs which are due to arrive in the next couple of days.
"With 3 CMEs already inbound, the addition of a 4th, full halo CME has prompted SWPC forecasters to upgrade the G2 Watch on 01 Dec to a G3 Watch. This faster-moving halo CME is progged to merge with 2 of the 3 upstream CMEs, all arriving at Earth on 01 Dec. G3 (Strong) conditions are now likely on 01 Dec."
NORTHERN LIGHTS POSSIBLE:
Heads up, friends.
A Class 4 Geomagnetic storm is headed our way for end of this week! There should be lots of nice aurora, even getting to mid-latitudes.
If you get to a dark sky, and have a phone that can do 30-sec exposures, you should be able to catch them. Point towards the N/S poles.

Last night was a delightfully pointless road trip with @bright_helpings
I heard about the #AuroraBorealis being particularly strong and visible across the UK that night. Aware of the full moon, I cross referenced a map of stargazing sites with cloud coverage to try and find somewhere cloud-free, and came up with Malham, a Dark Skies Discovery Site.
We drove there fuelled by #BBCRadio1 dance anthems and talking nonsense at each other. By the time we arrived, there was a light cloud cover, enough for the full moon to drown out the sky, so there was no chance of seeing the #aurora. Plus it turns out the site is south-facing.
We did see a lovely #MoonHalo, but so did @hag back home while walking Gary! After a while in the literally freezing car park, we headed home. The journey was more important than the destination and it was good to get E out of the house for a while and spend some time together.
Last night, the Aurora appeared over the north of Scotland. An almost full moon and plenty of cloud made photography conditions fairly difficult, but that’s part of the fun of Aurora photography. This shot looks north from the Black Isle towards the Cromarty Firth and Easter Ross.
Sometimes you just gotta sit on a bench beside the Observatory, eating fish & chips from a favoured chippy (Stefano's on Morningside Road) in a chilly -1ºC under light of a full moon whilst watching the remains of an aurora display as Orion rises.
