A fireball at night, brigter than the venus

4.10.2015 at 22.13 - 22.14 - Inari (III)
Juha Kinnunen, Jyväskylän Sirius

Not a fireball, but a nice-length stellar flight was recorded in three exposures as I was shooting a Northern Lights-time child. Vanana showed small brightening spots in the eye. Four-second exposures every 10 seconds: the first at 22:13:40, the second at 22:13:50, and the third at 22:14:00. NOTE! Since the Sky Watcher maintains that this is NOT a starburst ("We suspected there could be no starburst here, as more than 20s is a remarkably atypical duration for a starburst.") - and therefore the observation was classified by them as northern lights - I hope for views on what it is. In my opinion...

I noticed the first repos of the evening at about 7:30 p.m., and the show continued uninterrupted until at least 4:30 p.m., when I retired to a day’s rest. The Blue Corona at 8 pm made a special impression, as did the fact that most of the time the camera had to be pointed between the southeast and lunch - in Central Finland! I photographed them all with a 14-millimeter, which also became cramped at times.

The midnight nights were quite calm, but at midnight the activity increased significantly and continued fine over three o'clock. In the last two images, the direction is south, meaning the whole sky became covered. All images at 14 mm.

Half-sky auroras

Juha Kinnunen, Jyväskylän Sirius

In the early evening, only at most medium-sized openings were found in the cloud cover in the Jyväskylä region, so the large structures were not completely visible. However, the evening was remembered, in a special way: the Tikkakoski garrison and the Air Force base are nearby, where the day's air war exercise continued. Two fighters took to the air from the field and a pair of exercise-related red torches were fired from the same direction, which appear in the lower right corner of the first image. It was possible for the pilots to have a great view!

8.10.2015 at 21.15 - Multia (II)
Juha Kinnunen, Jyväskylän Sirius

At 9 p.m., there were a few short periods of activity on both sides, with a purple-edged arc at best, and a radial curtain whose tops were very blue in places, extending over 45 degrees. Beautiful autumn and spring phenomenon. However, there is nothing particularly impressive, covering the sky with Multia latitude. At peak times, I wasn’t in a decent shooting location yet, these images are from the downturn. After that, the sky was more or less empty. The cloudiness was 0/8 all the time, so you could admire the starry sky while listening to the Finland-Romania football match :-) In the low nor...

Quiet aurora band

13.10.2015 at 20.50 - Jyväskylä (II)
Juha Kinnunen, Jyväskylän Sirius

The diffuse arc brightened and activated promisingly at 20:50, after which a few dim blue rays rose to a maximum of 40 degrees. The joy, however, ended short as Bz rose north and the sky clouded. No information on the 'stripes' at the west end of the arc or anywhere else.

Memories from 10 years ago: a fairly ordinary northern lights show in Inari, seen from the West Bank of Lake Ukonjärvi.

Juha Kinnunen, Jyväskylän Sirius

Here are a few photos from October 22, 2001, which is one of the most impressive events of my repo photography career to date. The range of shapes and especially colors of the northern lights was more or less perfect - also a blood red rite from horizon to zenith, in many different structures. The wonderful, long screening included many really impressive moments, e.g. these crowns and a really solid dark red ray that remained in place for a long time. The cause of the storm was sunspot group no. 9661, in which two Earth-directed corona mass eruptions occurred within a short time, both with an ...

The ground weather was ideal - seven degrees warm, calm and clear - but in space weather a little handbrake was left on. This in itself pretty brightening was right after 10pm. I waited for the second coming until midnight, but it didn’t happen.

Juha Kinnunen, Jyväskylän Sirius

What is more comfortable in the midsummer frosts than reminiscing about summer and ... northern lights! I was on a business trip to Quebec, Canada in early June 2003, and one weekend I went on a trip to the wilderness, hoping to shoot repos for once in the middle of summer. There is enough light-free wilderness there and the sun's activity was also nicely elevated . Around Chibougamau in the latitude of Paris, I continued on the ‘ Route du Nord ’ from which I took these pictures, comfortably wearing a summer shirt.

13.10.2016 at 21.53 - Kyyjärvi (III)
Juha Kinnunen, Jyväskylän Sirius

This demonstration was an excellent example of how the Bz component of the interplanetary magnetic field alone can produce powerful northern lights. After all, both the speed and the density of the solar wind were at very normal levels all the time, but Bz was at the level of -10 ...- 20 continuously for as much as 12 hours. The road around Jyväskylä was in a cloud, so I drove in the direction of Suomenselä, and soon after Saarijärvi the sky became quite clear. In many places, however, there was dense fog.

Auroras seen through breaks in the clouds

27.3.2017 at 22.46 - Kuortane (II)
Juha Kinnunen, Jyväskylän Sirius

The activity in the afternoon was so good (Kp = 5 ... 6) that I drove from Jyväskylä in the hope of a clearer sky towards Ostrobothnia. Over the course of the evening, however, the clouds increased there as well and Bz began to spend an unauthorized amount of time on the north side. The best brightness was almost completely in the clouds at my scene, this screen is about its after-heat.

The glory that hit the strikes at 11pm was pretty nice to see. Figure 2 is from Jyväskylä (20:46), others from Konnevesi.

These repos were very quiet - the forecasts allowed me to expect much more - but it was nice to see these after the summer break as well. The conditions were right - dark, clear, warm (13 C) and calm, on the neighboring beach the Venetians will still be crowning the atmosphere.

The show started reasonably promising, soon after nine o'clock, but a fairly dense cloud cover spread to the scene as early as an hour later. Expectations were higher.
