What are the best cameras and lenses for aurora photography? How about at different price points? Let's break it down, but first, read my blog article about it: theauroraguy.com/blogs/blog/m...

This is what October 2026 looks like IRL for my calendar…. Launching in two days, and I can’t wait!

I don't think we see anything more than G1-G2 storming from this event. Maybe we won't see even G1... time will tell!

Vincent Ledvina @vincentledvina.bsky.social · 5h

Interestingly, it looks like NOAA SWPC *removed* their period of G1 storming from the 3-day Kp forecast... they may think the influence from the coronal hole won't be as drastic. We'll have to see what happens, but I just thought this was interesting.

Quiz for all of you:

True or false? The OVATION model can show substorm activity.

Let me know you thoughts in the comments. I will post the answer later today!

Traveling to Fairbanks soon? Consider booking a tour with us!

Maia and I are partnered up this season to run aurora tours. October is a great month for aurora viewing. Even cloudy conditions are workable with Maia able to seek out clear weather.

There have been many substorms over the past nights as well. In fact, we may have experienced a "sawtooth event" last night which can happen under steady Bz south conditions. Learn more about this special magnetospheric mode: go.theauroraguy.com/october2024s...

Vincent Ledvina @vincentledvina.bsky.social · 1d

Impressively, the Bz has been south almost 100% of the time over the past 24 hours. Despite relatively average solar wind conditions otherwise (speed ~400 km/s; Bt ~ 8 nT), the aurora has made an appearance above the 45th parallel two nights in a row.

Substorm happening now as seen in Ely, MN with large pillars stretching into the sky. Nice! Head outside and take a look if you can.

There is an auroral arc extended off the horizon now in Ely, MN on webcam. It may be worth at least a quick peek outside at this if you live above the 45th parallel. During a substorm, the view may become quite nice. GOES values are very low now.

Here is the scale of the coronal hole moving to face Earth in the coming days compared with the size of Earth itself. It's a decently-sized coronal hole, but not exceptionally large by any means. Still, it may spark minor to moderate geomagnetic storming this week! Stay tuned...

I've found a few more webcams around Alaska and Canada today! Here is one near Rampart House, Yukon which can show aurora very well. The panoramic views update every five seconds. Very nice resources!

You've seen VIIRS imagery from geomagnetically-active times, but what about during a quiet night of aurora? Can you see it? This is what the auroral oval looks like during steady-state quiet conditions... I indicated the upper and lower boundaries with arrows.

There are some smaller CH to the west of the main CH85 that may pepper us with some fast wind streams beforehand, too. The intrusion of AR 4243 may make the solar wind profile at L1 a bit more complex. The waning moon will make viewing a bit easier, too.

The coronal hole which caused a G3 storm last month is back and soon to face Earth! We may begin to feel its effects by the end of the week/weekend. We may see G1-G2 conditions from this feature, I think.
