Last night, while you were sleeping, the northern lights sparked stunning displays visible to the eye along the shores of Lake Huron. Captured in Saugeen Shores, Ontario Canada July 23, 2025 @ 12:15AM #NorthernLights

Plenty of sunspot regions on the visible disk, none of which are particularly active though. Right now I'm mostly interested in ARs 4142 and 4143, 2 regions that are currently growing well. Only weak C-flares from these so far, but this could change if they keep developping.

"The Witching Hour" Jumping Pound Pond, West of Calgary, 0250713T0600Z As the clock strikes midnight the sky is alight with strange blue nitrogen pillars, visible to the naked eye these were worth the trip out West to shoot the aurora. @randymilanovic

Jumping Pound Pond, West of Calgary, 20250713T0550Z Although the data wasn't that great and the Bz had swung North I did manage to catch a short substorm that had pretty decent pillars. The substorm lasted all of 15-20 minutes. #Sun #Spaceweather #Aurora #Auroraborealis…

The Northern Lights made an appearance, this far south, last night and early this morning. (Camera Only) Delton, Michigan July 22-23, 2025. Pic 1: 12:37 am. Pic 2: 11:03 pm.

Gorgeous aurora images from 7/23/25, Mt. Rainier National Park , Washington-elevation 6400 ft.

Our Sun has been busy today releasing multiple CME's from filament releases, these were all from different areas of the Sun, unfortunately none of them appear to be Earth directed. #CME #Sun #Spaceweather

Not sure what is in store for tonight aurora wise in the mid latitudes. Things are definitely not looking good there is an off chance of catching a substorm, but that is a bit of a stretch. #Aurora #auroraborealis #northernlights

Very brief (less than 10 mins) #aurora substorm in Goshen, MA. Second one of the night with little activity in-between. Taken on 7/22/25 at 11:04PM EDT.

It appears that we will have a show sometime the night of the 26th

A filament eruption was observed near 23/0500 UTC centered near N07W02. A possible associated CME was observed in STEREO imagery beginning near the same time. However, no discernable ejecta was visible in LASCO imagery. Analysis is ongoing at the time of this summary.

As per my previous post it appears that we are seeing the CH HSS CIR, didn't start out as much but as the CIR arrived the Bt and Bz reacted, and we are seeing G1 conditions, there may be a slight possibility of a brief excursion into G2 conditions. We should see aurora in the…

Trans-equatorial Coronal Hole 66 has turned centre disk and it's Coronal Hole High Speed Stream (CH HSS) is on it's way to Earth, the CH HSS CIR should arrive in 2-3 days. As this is a trans-equatorial CH there is a very strong possibility of G1 conditions. #CHHSS #Sun…

"Convergence and the NLC's" Rocky Ridge Calgary Alberta 20250717T0515Z The Convergence Sculptors in Calgary are one of the many pieces of art that the City of Calgary commissioned. These two pieces sit above the Calgary YMCA in NW Calgary. I have captured the NLC's here several…

Well the Filament lifted off and is headed north of the Earth Sun line, with a slight possibility of a glancing blow at Earth. The speeds varied between 200-1953 km/s

Well look who's not sticking around, it appears the large filament in the NW is in the process of lifting off will it throw something in our direction? #Sun #Spaceweather #Filament #CME

A combination CME from behind the limb that triggered what appears to be an Earth directed filament release. Unfortunately the CME is travelling South of the Earth Sun line..... meanwhile there is a massive filament hovering in the NW. #CME #Filament #Sun #Spaceweather

A solitary pillar has been hanging around for 20 nin

Boon and just like that the aurora fires up
