Comet C/2022 E3 (ZTF) as seen from the Ulvila observatory. In light-polluted conditions, the comet was mostly only visible as a round, hazy coma. No visual tail was seen. It is difficult to tell where the comma begins and ends, therefore determining the diameter of the comma is difficult. The diameter of the coma is conservatively estimated from the drawing. In the middle of the coma, a bright central brightness. The brightness of the coma increases strongly towards the center. The comet was moving quite quickly at the moment of observation and the movement could be easily detected during my o...

Southern Finland also got its share of pearly clouds in the afternoon of January 26, 2023. Pearly clouds could be seen in the western direction. The pearls appeared to be mainly type I pearls.

My second observation of comet C/2022 E3 (ZTF), this time finally under dark skies and without hurry. The first thing you notice about the comet is a round, hazy coma with a clear central brightness in the middle. The coma brightens rather sharply towards the center. The comet seems to be leaving a very dim and faint tail in the northwest direction. The tail is so flimsy that it is hard to tell how far the tail continues, but I estimate the length of the tail to be approx. 16'. I also made a brightness observation of the comet with 10x50 binoculars. The observation method is the imprecise-...
Telescopic comet ZTF

Juha Ojanperä, Porin Karhunvartijat
My first observation of Comet C/2022 E3 (ZTF). Kiirus meant to come with an observation, I looked that there might be a small clear moment just at the beginning of the astronomical twilight. In a hurry, I packed my things and headed towards Nakkila. After arriving at the observation site, it was a hurry to set up the equipment for the observation and look for the comet. In addition to the approaching clouds, the difficulty factor was increased by the dusky sky, the scattering of light pollution on the horizon in the direction of the comet and the fact that the comet was low. I almost managed t...

The first northern lights of the year appeared in the sky on the night of February 1/2, 2023. The Northern Lights were pretty modest, but it all counts! During the night, a calm aurora arc/belt was visible low on the northern horizon.

Visual observation of Mars at night on 12/13/11 2022. Seeing was quite good and details stood out nicely. In the drawing, north is at the top. The angular diameter of Mars at the moment of observation is 16.3''.

The morning dawned cloudy and rainy in Ulvila. I thought I wouldn't let the elf take away today's solar eclipse from me, so I took the reins into my own hands. After looking at the satellite images, I decided to drive towards Vaasa, where according to the satellite images it would be clear. I drove towards the north racing against the clock and the clouds. In the end, I found a suitable observation spot in the area of Mustasaari municipality, approx. 20 km south of Vaasa. When I got to the place and got the observation rigs together, the eclipse had already started. I was able to see t...

I was photographing the northern lights on the shore of Lake Palusjärvi in Kullaa, Ulvila. It happened once that a fireball hit directly in the middle of the camera's frame and the exposure was in progress. Jackpot!

On the night of 23/24/10/2022, I was finally able to spot a little better aurora borealis, this time finally in a dark place in the scenery of Palusjärvi in Kullaa, Ulvila. During the show, a calm arc was first visible, which slowly rose up in the sky and became an active belt at approx. 23:23-23:40. In all the hustle and bustle, I forgot to put on the anti-fog collar to warm the lens right away, and because of this, unfortunately, the lens fogged up during the most active phase. I put the anti-fog collar in place, but the lens warmed up slowly and that's why there was a frost strip in the...

Visual observation of Jupiter at night on 18/19/10/2022. The northern and southern equatorial belts were nicely distinguishable in detail, although there was no peak viewing during my observation.

The opposition of Mars is already looming about two months away. So it's a good time to start observing Mars! My first visual observation of Mars since opposition 2020. The angular diameter of Mars is still small (at the time of observation about 13.1"), but on the Ulvila observatory's Celestron (280/2800 mm) details were still moderately distinguished, even though the seeing was only average and Mars was only at an altitude of 17 degrees. By comparing my observation and my drawing with the Mars map, I was able to state that I have seen at least Syrtis Major and the plain of Hellas. Th...

I finally managed to make a visual observation of Jupiter with Ulvila's 280 mm Schmidt-Cassegrain (Celestron C11). During my observation, Jupiter is at an altitude of approx. 20 degrees. Seeing was mediocre, but you could make an observation. The great red dot was just turning out of sight. The details of the northern equatorial belt stood out nicely. The southern equatorial belt also seemed to be visible quite well, especially compared to my previous observations with the 154 mm Cassegrain. Em. with a smaller Cassegrain, the southern equatorial belt has appeared dimmer relative to the nor...
