A fireball at night, as bright as a crescent moon

1.12.2021 at 17.07 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

Also seen in Nenäinniemi's allsky camera, unfortunately behind the gauze.

A fireball at night, brigter than the venus

28.11.2021 at 19.53 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

This has presumably been quite bright as it is well visible through the clouds.

A fireball at night, brigter than the venus

26.11.2021 at 17.30 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

There were already several observations of this. The image of the Nyrölä Observatory meteor camera had also hit.

Telescopic comet Leonard

22.11.2021 at 05.20 - 06.09 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

I also photographed this in a timed morning, as the comet C / 2021 A1 (Leonard) is quite low in the early evening. Hopefully the weather will allow this observation in the coming weeks, as the forecasts promise a comet of about 4 mag brightness, the most optimistic even 1 mag.

Telescopic comet Churyumov-Gerasimenko

22.11.2021 at 03.39 - 03.48 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

The telescope photographed two brightest morning comets from the backyard in a timed way while Vetel himself was struck.

Several halo forms

20.11.2021 at 22.00 - 23.15 - Hankasalmi, Murtoinen (II)
Harri Kiiskinen, Jyväskylän Sirius

A short-lived halo around the moon from 22:00 to 22:30 and from 23:00 to 23:16. A weak 22-degree ring can also be seen in the pictures taken at 00:28, 04:52 and 04:59. Radio telescope tracking was adjusted from time to time, so the cover is not in front of the Moon in all images.

One halo form

9.11.2021 at 10.35 - 11.40 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

The 22-degree ring shone in the sky for just over an hour. No other halo shapes were found in the image stacks.

Telescopic comet Churyumov-Gerasimenko

8.11.2021 at 22.14 - 22.51 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

The brightest comet at the moment and even a fine tail seems to be. The comet is probably at its brightest right now, as the periheli was 2.11 a week ago. and the closest comet to the country is 12/11/2021 Light curve: COBS. SI

Telescopic comet Helin-Roman-Alu

8.11.2021 at 22.02 - 22.10 - Hankasalmi, Murtoinen (II)
Harri Kiiskinen, Jyväskylän Sirius

Comet 132P is currently cooling behind the orbit of Mars and is a rather modest target. The periheli of this is also a point (13.11.2021), so this does not become more strange. Light curve: COBS. SI

Telescopic comet Schwassmann-Wachmann

8.11.2021 at 21.51 - 21.59 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

Comet 29P has had several outbursts in recent weeks, but no observations have been made of Finland. Finally a bright evening came and I was able to spot the comet. Compared to my previous observation on October 3, 2021, the comet has brightened slightly and the coma has clearly expanded. We hope that there will continue to be plenty of observation.

Telescopic comet PANSTARRS

8.11.2021 at 19.01 - 19.16 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

Comet C / 2027 K2 brightens very slowly, and in about a year's time it is forecast that the level will reach 5-7 mag, depending on the forecast.

Several halo forms

6.11.2021 at 10.07 - 10.37 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

For a long time the sun mocked and the 22 degree ring and overhead were visible for half an hour. The harvest of a broken halo camera.

Several halo forms

24.10.2021 at 13.00 - 13.30 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

The catch of the new halo camera from Fractions. The camera follows the Sun on a radio telescope.

Telescopic comet Schwassmann-Wachmann

3.10.2021 at 22.10 - 23.01 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

Finally the weather was clear and I was able to detect a comet 29P superburst. My previous observation of this comet was 9/9/2021, when the brightness was 13.4 mag and now less than a month later on 3 October 2021 the brightness has risen to the level of 10.7 mag. The diameter of the head is currently just under an arc minute and is expected to increase and dim in the near future. Hopefully the weather will allow for regular observation of this interesting comet in the coming weeks. Light curve: COBS. SI (own observations in blue, KIIaa). Brightness determined with KOPR program.

Auroras seen through breaks in the clouds

8.9.2021 at 03.35 - Jyväskylä (II)
Harri Kiiskinen, Jyväskylän Sirius

The SAR arc is annoyingly behind the cloud.

Telescopic comet PANSTARRS

4.9.2021 at 00.28 - 00.34 - Hankasalmi, Murtoinen (II)
Harri Kiiskinen, Jyväskylän Sirius

The remote observation season in Hankasalmi has started and comet observations have already been accumulated on four evenings. This C / 2020 PV6 (PanSTARRS) is quite opaque, but a clear tail is noticeable. The comet's perihelion is at the end of the month, so this hardly gets much brighter from this. Light curve from the COBS database, own observations in blue.

Telescopic comet PANSTARRS

4.9.2021 at 00.21 - 00.27 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

The brightness of this comet is slowly increasing and at its brightest it is expected to be around 7 mag around the turn of the year 2022-2023.

Telescopic comet ATLAS

4.9.2021 at 00.08 - 00.16 - Hankasalmi, Murtoinen (III)
Harri Kiiskinen, Jyväskylän Sirius

The brightest comet currently visible in Finland. Periheli is in early January 2022 and this is projected to brighten just to the right of mag 10.

Telescopic comet Leonard

1.9.2021 at 23.39 - 23.45 - Hankasalmi, Murtoinen (II)
Harri Kiiskinen, Jyväskylän Sirius

This was found in January of this year and the brightness hurts during the fall and early winter to 10 mag to the right. If the predictions are correct, then around Christmas we will be at the level of 4-5 mag.
