G1 Geomagnetic storm 31st October 2021
Here are my magnetometer data over the period 30th October to part way into November 1st which includes the expected CME(s) from solar flares occurring on/around 28th October, one of them being an X-class flare.
The 'Halloween' storm as of yesterday was more intense and longer lived than the one on the previous night that Mark witnessed on the ground in Iceland. Maybe this one was the expected 'big one', but at G1 level it was still rather modest.
Anyhow, both show up rather well and it's interesting to see their quite different characteristics.
Thanks for looking.

Re: G1 Geomagnetic storm 31st October 2021
Very interesting Stu, so I wonder if the first Aurora actually (soften the atmosphere - so to speak) effectively minimising the effect of the second Aurora (from AR2887) and preventing that one from the "Big display" ??
Certain during some daylight-hours Aurora was likely to have been visible..
Thanks for your efforts

It is odd that we didn't get much more of an event, I bet the scientists will be mulling over their predictions this week

Re: G1 Geomagnetic storm 31st October 2021
I see that the Southern Hemisphere was lit-up with Aurora - so perhaps it was split-up half north and half south He He..
Alexandra, as the Earth's meteorologists don't het it right all the time, then why should the Aurora guys/gals get their offerings better ??
I mean, 93-million miles is a long way to travel over two or three days and maybe the Solar-wind can drift off-course, but hey what do I know, as many people don't always cross a road by the shortest distance - after a glass of whatever...

Great data Stuart
Looking back on it, the more hyped an astro event is made out to be before it occurs usually leads to a less than impressive event in reality
How many comets of the century, etc, get announced only to fizzle? It is the ones that come out of no where that usually put on the best show! A lot of variable at play with this event and it didn't turn out nearly as hoped. At lease Mark got some nice action captured under the aurora!

Thanks for the data Stu, seeing that first big peak of the CME on the Lancaster graph was what sent me outside looking, b#y midnight it was all pretty uneventful again though...

Re: G1 Geomagnetic storm 31st October 2021
Yea….when I saw how rapidly things had settled at 2:00am UT when I woke in the night, I suspected that the show was over, despite the hype that this was going to be a significant event. The next one is in transit, so we’ll see how that goes.marktownley wrote: ↑Tue Nov 02, 2021 9:10 pm Thanks for the data Stu, seeing that first big peak of the CME on the Lancaster graph was what sent me outside looking, b#y midnight it was all pretty uneventful again though...

Apparently the next Aurora is likely from 23:00z tonight 3/11/2021...

There's not many nights we don't get an aurora under the auroral oval, it's just where that oval is and how powerful...EGRAY_OBSERVATORY wrote: ↑Wed Nov 03, 2021 10:20 am Apparently the next Aurora is likely from 23:00z tonight 3/11/2021...
