Hey, everyone! I am happy to announce that I am partnering with another aurora guide this season - Levi Johnson! Levi's aurora tours are launching TONIGHT, and there is availability all season.

So, the Maine camera is “stuck” on a frame from Nov 25, but on the Isle Royale cam, there is some glow visible behind the clouds.

There is maybe the *slightest* glow of aurora below horizon cloud cover on this webcam in northern Maine. Mid-latitudes isn’t missing much so far, but substorm activity could provide brief, on-camera visibility for chasers north of the 45th parallel.

Solar wind conditions are looking awesome for high-latitudes and favorable for some minor mid-latitude auroral acricity, especially during substorms! If the turkey hadn’t tired you out, maybe stay up and keep an eye on webcams once it gets dark :)

AR 4291 may be one to watch as it has developed into a beta-delta region recently. This means opposite polarity magnetic fields are close together, an unstable configuration that can lead to intense flare activity. Right now, AR 4291 only has a 15/1 % chance of M/X-class flares.

Happy Thanksgiving, everyone! Thankful for all of you today and every day 🙂 and for this awesome aurora chasing community. You all rock! I hope everyone has a great day even if you don’t celebrate Thanksgiving.

Did you see little green blobs during the big storm a couple weeks ago? Well, they may have been FAEs, or Fragmented Aurora-Like Emissions, and your photos are helpful to scientists!

The aurora last night (Nov 26-27) as seen by the NOAA-21 satellite. You can see it was a pretty bright night with the auroral oval not too extended beyond the normal range.
Yellow areas indicate brighter emission (aurora and city lights) while blue/black areas are darker.

We are still feeling the effects of CH 98 and CH 99 and have now entered a "HILDCAA Event." This is something that I will define more in future blog posts and e-books, but the acronym stands for "High Intensity Long Duration Continuous Auroral Activity."

Tonight in Fairbanks there was a rare 6 pm substorm! This coronal hole is causing some spectacular auroral displays for high-latitudes with likely HILDCAA pattern with frequent substorms.

Wow, stunning aurora tonight in Fairbanks on Maia's tour! Check out the amazing aurora reflections still in December. Open water exists if you know where to find it :)
Book a tour with Maia this season! We have lotws of availability next month!

The solar wind speed is absolutely cooking this morning. 800+ km/s!

The aurora at mid-latitudes is a bit subdued so far tonight. Here is a live look at the northern horizon from Isle Royale in Michigan: go.theauroraguy.com/webcams .

Quick update: the high-speed solar wind from the coronal holes has arrived a bit earlier than expected. Speeds are now in excess of 700 km/s. Some auroral displays may be possible for the northern tier of the U.S. tonight.

Hey, everyone! One of my friends, Dr. Claire Gasque who is a scientist studying the aurora at UC Berkeley has a request and needs your help! She is looking for pictures of a STEVE event which occured on the night of August 29-30, 2024 over Alaska and northern Canada.

Some nice aurora in Porjus, Sweden now fueled in part by the ongoing effects of the coronal hole high-speed stream. These CHHSS events are particularly nice for high-latitudes.

Here's what the aurora looked like last night in Ely, MN, close to the U.S.-Canada border. Views like these are possible tonight as well, perhaps with the aurora stretching even higher in the sky since solar wind conditions have become more favorable. Let's see!

Currently, the solar wind magnetic field is elevated, and GOES mag readings indicate that there is enough "charge" in the system to fuel a substorm, maybe within the next hour. If you're above the 45th parallel and are a dedicated chaser, monitor webcam activity and GOES mag.

There's a bit of glow on the Isle Royale cam in Michigan right now! This is likely due to the elevated IMF and some recent south Bz conditions. Take a look at live webcams and if you're along the U.S-Canada border, you have a shot at activity right now.

There are some new sunspot regions emerging in the Sun's east! The SSN nearly doubled in the last few days. Will these active regions manifest into major flare players? We'll see! So far, AR 4290 and 4291 are the most promising of the bunch. AR 4291 has a 15% chance of M-flares.

Positive-polarity coronal holes 98 and 99 are now facing Earth and sending fast wind our way. This solar wind enhancement may reach us in 2-3 days and cause G1-G2/Kp 5-6 conditions. We are already seeing a field enhancement likely caused by an SSBC. More activity may be coming.
