"In The Colours Of A Rainbow?"
Sibbald Pond West of Calgary 20251113T0130Z
Rarely does one capture such a variety of colours in the aurora, the Rayed Arc "Curtain", filled the Western horizon for an hour, there was no real activity in the East.

The Remembrance Day Storm of 2025 will go down as one of the most unique geomagnetic storms for its ferocity without knocking out major power systems.

Rarely does the the aurora explode this fast, the peak of the substorm lasted all of 10 minutes.... it leaves one gob smacked, and one questions "What is Reality"?

Watch the Sun and remember that Coronal Holes(51 and 52) that are negative in the Spring, and are Transequatorial, produce magnificent geomagnetic storms.

Great article on Cecilia Payne, who discovered that the Sun -- and therefore stars -- is made of hydrogen and helium.

The greatest astronomy PhD ever written
Cecilia Payne realised that the Sun and stars are primarily hydrogen and helium - only for a man to take credit for the discovery

"Caught In Between"
Last night West of Calgary Seebe, Alberta, this is a SAID arc in an enveloped auroral arc, or something. First time that I have seen anything like it, my camera is pointing NNW for the first shot, time 20250501T0540Z, the second shot is taken to the ESE, the time was the same.

"Like I SAID"
Northeast of Calgary 20250418T0520Z
At the end of the first substorm a SAID aka STEVE formed and stayed visible for about 30-40 minutes. It was difficult to make out with the eye, so I set my camera's to ISO 5000, F2.8, 13-15 seconds. There was no Picket Fence that I could see.

It took awhile for the charge to build but when the substorm hit it was a beautiful sight to behold. This was a night where the pond was as still as a reflection in a mirror, and I was fortunate enough to be able to capture the aurora.

It appears that the culprit behind the Northward trend in the BZ is a CIR From Coronal Hole 35. Notice the rise in density and the drop in the solar wind speed usually indicative of a CIR

How about that folks the field finally turned in favour of an auroral show at upper lower latitudes. If this was later in the day this would be a "Get Out There" post. Sadly we will have to sit on our hands and sweat it out till it gets dark, here's hoping! #Aurora #Auroraborealis #northernlights

This bodes well for those in the West. It appears that the main bulk of the CME is 4 hours behind the initial bulk.
