A fireball at night, as bright as a cresent moon

19.9.2018 at 01.28 - Paimio (IV)
Mikael Pekkala, Ursa (Etelä-Suomi)

I was outside telescoping and photographing the sky when suddenly a bright spot appeared to the west that brightened at a rapid pace. The first thought was that it was a flash of an Iridium satellite but as the brightness just continued I realized it was a fireball. Walked surprisingly slowly compared to other fireballs I’ve seen. It took so long (3 s) that I could already think of having to turn the camera towards it. But still, I was so confused to see that I couldn’t take my eyes off it, so I didn’t start to turn the camera. It is questionable, by the way, that I would have had time to do i...

Partial solar eclipse

11.8.2018 at 11.50 - 12.45 - Raisio (IV)
Mikael Pekkala, Ursa (Etelä-Suomi)

At first I thought it wasn’t worth going to even watch this “mini” eclipse, especially when a cloudy sky was predicted. But the morning was surprisingly clear and less frequent is here in these chores suitable temperatures, so nothing more than a tube out and detect. It was worth it.

Moon

14.11.2016 at 16.40 - 18.00 - Turku (III)
Mikael Pekkala, Ursa (Länsi-Suomi)

Super moon observed from the Marjaniemi bird tower in Ruissalo. At first I assumed the sky was so cloudy that nothing was visible, but luckily I was wrong. When the clock came at 4:40 p.m. Then I only realized that it is the moon :) Images slightly processed, including light added to the dark and bright spots dimmed. Lens color defects reduced. The noise is pretty loud in the pictures I took with PowerShot and I didn’t start to remove it terribly.

Perseidit

16.8.2015 at 01.31 - Raisio (III)
Mikael Pekkala, Ursa (Länsi-Suomi)

The camera was shooting in a timelapse position with northern lights heading north. At the same time, this meteor had been recorded, which, judging from the direction of arrival, belonged to the Perseid star flock. The same meteor is apparently also present in this observation: http://www.taivaanvahti.fi/observations/show/41113 . It is special that in my own pictures (unlike Jouni Hovi's observation) the meteor only appears in one picture. The camera was taking pictures with a 16-second exposure. There was a 4 second pause between images. To justify a closer look at the metadata, this imag...

Partial solar eclipse

20.3.2015 at 12.07 - Loimaa (IV)
Mikael Pekkala

I drove the clouds from the south to Turima to escape to Turimaa. This helped so much that I was able to see until the end of the eclipse under reasonable conditions. I was a little late from the beginning of the eclipse, though. During and after the eclipse, a 22-degree ring was also visible around the sun.

All-sky aurora

17.3.2015 at 22.00 - Nousiainen (V)
Mikael Pekkala

I finally got a report on this tough class Northern Lights play. I have never seen such a great northern lights show before. Even the Northern Lights show, exactly two years ago, wasn’t that great. Northern lights were visible all over the sky and I couldn’t decide which direction of the sky I would point with the cameras. Amazing! Here's a time-lapse video I made: https://www.youtube.com/watch?v=wkgZzzbZabc

Sun

12.3.2015 at 10.10 - Raisio (IV)
Mikael Pekkala

Practice for next week’s eclipse. Everything seemed to work well. The white balance of the images is adjusted slightly to yellow. I think this way the sun looks a little more natural than the images that have not been processed. Images taken through the astrosolar membrane when appear to remain slightly gray. Figure 1: The whole sun. Figure 2: Larger magnification using 2x Barlow. Figure 3: Same as Figure two except for dust and debris caused by backpacks edited out of the image. Sometimes it would be good to clean the lenses :)

Eye-catching night shining clouds

12.7.2014 at 01.09 - 03.06 - Raisio (V)
Mikael Pekkala

Now there is such a mood in the sky that everyone looks out. I'll put in better pictures when I have time. Edit: Images added. By the way, it was the brightest and widest night cloud show I saw. Thanks to the people whose prompt reporting allowed me to see and experience this.

Auroras seen through breaks in the clouds

14.10.2013 at 23.40 - Raisio (II)
Mikael Pekkala

Before going to bed, I quickly decided to go outside to take a look if even the northern lights were visible. I took a few pictures and nothing stuck to them so I decided to go back inside. Just as I was leaving, I saw what a strange laser beam appeared next to Otava's bucket :) At the same time I realized there was a northern lights in the sky. For a moment, there were faint northern lights between the clouds that quickly changed shape. After 10 minutes, the clouds completely covered the sky and I stopped observing.

Moon

24.8.2013 at 21.30 - Turku (IV)
Mikael Pekkala

Once again, the observation trip was to the Ruissalo bird tower. While watching the sunset, I happened to glance at the opposite side of the sky. Surprisingly, the Moon had risen below the horizon and now shone next to Turku Cathedral (Figure 1). There was a great opportunity to immortalize the Moon above the roofs of Turku. I hadn’t planned a description of the situation in advance, but it was pure coincidence. From the second image, the eye can distinguish at least the following landmarks: Midsummer Hill, St. Michael's Church, Cathedral, Vartiovuori Observatory, Kakola, Pääskyvuorenlinkk...

M45

13.8.2013 at 01.26 - Turku (III)
Mikael Pekkala

M45 or "Sifters" or "Pleiades" or "Seven Sisters" or "Little Otava" (the beloved child has many names). I tried how to capture that subject with the SX50 without a tracking tripod in a swaying bird tower. Here is the result, i.e. it succeeds but the noise gets terrible due to the high ISO value. 6 images with a 1-second exposure and an ISO value of 3200 were taken in this image. I sometimes have a better time trying to shoot with a tracking stand on a sturdy surface. Figure 1 is stacked. Figure 2 is a single image.

Clearly visible night shining clouds

13.8.2013 at 01.08 - 01.41 - Turku (III)
Mikael Pekkala

In addition to all the lightning and star flights, there were illuminating night clouds in the north. Figure 1 at 1:18 p.m. Figure 2 at 1:19 Figure 3 at 01:41

Meteor image

13.8.2013 at 01.06 - Turku (III)
Mikael Pekkala

Several starbursts were seen while watching from the Ruissalo bird tower, but here is the only one who agreed to hit the area photographed by the camera. The direction of the picture is south.

Satellite

13.8.2013 at 01.04 - Turku (III)
Mikael Pekkala

The camera was set to take pictures facing south in hopes of assholes and lightning. Yes, they were also visible, but a piece of the Earth's orbit also came into the picture field. On closer examination, the piece was confirmed as space debris. According to the Heavens above site, this is the Meteor 1-24 Rocket, which is a rocket phase launched by the Soviet Union in 1976. That song appeared in 10 images stacked in Figure 1. Figure 2 is the same image cropped.

At least 10 lightning strikes seen

12.8.2013 at 23.10 - Turku (III)
Mikael Pekkala

The intention was to watch and photograph the starfight of the Persians from the Ruissalo bird tower, but the attention was drawn to the Kalevant fires flashing in the south and southeast. In addition to the back flickering of the clouds, a few discharge channels were also visible (Fig. 1). Figure 1 at 11:10 p.m. Figure 2 at 00:23. Figure 3 at 1:03 p.m. From the beginning of the night, there were other people present watching the sky. In addition, during the eventful night, other phenomena (including illuminating night clouds and persides) had to be seen, from which I made separate observation...

Image of an exceptional thunder cloud

5.6.2013 at 20.50 - 22.06 - Raisio (IV)
Mikael Pekkala

A thunderous cell was heard from time to time in the eastern part of Turku, but I did not see lightning. In any case, the prey became handsome cloud formations. I noticed two anvil-shaped clouds merging together as well as mammoth clouds on two occasions. Figure 1: Two panoramic images, the upper at 20:50 and the lower (sorry for the connection error in the image) at 21:21. Figure 2: Larger image of a mammoth cloud that appeared at 9:21 p.m. (also shown in the lower panorama of the first image). Figure 3: At 22:01 a mammatus cloud appeared which was clearer than before. Figure 4: Larger image ...

Sivusateenkaari

24.8.2012 at 20.05 - 20.25 - Raisio (IV)
Mikael Pekkala

A special ray seemed to emerge from the main rainbow towards the center of the arch. The highest point of the rainbow was not visible, only both ends of the arc were visible. The "radius" was visible in both halves of the arc, though the left side was dimmer. A side rainbow was also visible. The "ray" disappeared from view first, then the side rainbow, and finally the main rainbow itself. Before the appearance of the rainbow, large droplets seldom rained.

Transit overcast

6.6.2012 at 06.20 - Turku
Mikael Pekkala

The weather forecast had promised a thick cloud cover over the Turku region in the morning. Despite this, I tried my luck. A closer observation of the predictions, namely, showed that, Cloudiness is slowly receding from the southwest direction from six o'clock onwards. So I had to get as far as possible to the archipelago, but not too far because I still had to get to work. Of course, we still had to find a good place to observe. The compromise solution was a field in Hirvensalo, Turku. When I arrived at the scene at 6:20 it was cloudy, but little hope was aroused by the reflection of ligh...

Partial lunar eclipse

10.12.2011 at 17.58 - Raisio (III)
Mikael Pekkala

The sky was really cloudy, so I didn’t bother to go out to try my luck. Surprisingly as I sat inside, I noticed a faint reflection in the sky, so suddenly I grabbed the camera and took a few pictures through the window. The perfect phase had already passed by this point. Only a small part of the full shadow hit the upper right corner of the moon. (This, too, was partly behind the branches in the pictures.) Of course, as soon as the eclipse passed, the clouds tore, revealing the full moon.
