Binocular comet NEOWISE

15.7.2020 at 01.00 - 02.00 - Äänekoski (I)
Juha Kinnunen, Jyväskylän Sirius

In Koti-Jyväskylä, the northern sky was quite cloudy at midnight, so I dared to drive even further north, and Äänekoski was quite clear. However, even at this darkest hour, the northern sky was so bright that it was impossible for me to detect NEOWISE, or a little behind it. Sure, Capella was visible to the naked eye and Menkalina, especially with my little binoculars, but the comet's observation was very fragile: a couple, three times I think I saw it extremely weakly with binoculars, but I can't be sure. I took pictures in the best shotgun shooting style and will add a snapshot to th...

All-sky aurora

17.3.2015 at 19.56 - 03.55 - Viitasaari (V)
Juha Kinnunen, Jyväskylän Sirius

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.

Clearly visible night shining clouds

There may have been nights in a wider area, but the rest of the clouds covered the sky.

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...

Active aurora band

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.

Juha Kinnunen, Jyväskylän Sirius

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.

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.

Total lunar eclipse

Juha Kinnunen, Jyväskylän Sirius

Moon and Mars together at 23:53, 00:10 and 00:26. What was the picture when the air temperature was +22 C at midnight. Although my observation site was practically clear, there was apparently enough auerta or cloudiness in the southeastern horizon, and the Moon so dim that I only noticed it until 23:40.

Half-sky auroras

7.10.2015 at 21.11 - Jyväskylä (IV)
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!

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.

22.10.2001 at 21.00 - Jyväskylä (V)
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.
