(7482) 1994 PC1

18.1.2022 at 22.31 - 22.37 - Ikaalinen (III)
Jarno Paananen, Tampereen Ursa

Between the clouds, an asteroid (7482), which had quickly passed by ex tempore, was quickly overtaken in 1994 by more than 1.9 million km. I didn’t have time to tune the orbital elements to the pedestal, so I contented myself with photographing the asteroid as a streak with regular tracking. I also tried using the PHD2's comet tracking to track it, but that didn't quite follow. The hole in the clouds didn’t last long, but the second image is the sum of a five-minute shot. There was so much momentum that there was a clear gap between downloading the image from the camera.

A fireball at night, as bright as a cresent moon

The image of the celestial camera, a little dew and a cloud above, when the stars are barely visible, Mars can be seen below it. The picture shows north at the bottom, so the direction is southeast. 10s exposure, timestamp end of exposure, no trace in previous or next image.

This ball, already familiar from tea water, had been left in the sky camera.

Perseidit

There were a few Perseids left in the sky camera, this was the brightest of them, even in the next 10s exposure it was still clear as smoke.

Binocular comet Wirtanen

26.12.2018 at 00.53 - 02.03 - Ikaalinen (IV)
Jarno Paananen, Tampereen Ursa

It was clear for a while on Christmas Eve and Wirtanen was aptly at the meridian and no longer right next to the Moon, so I had to try to describe this in a bit of color.

A little ball tail left in the corner of the sky camera.

There was a ball left in the sky camera for a change.

This little streak had remained in the sky camera as well.

Iridium 64

Jarno Paananen, Tampereen Ursa

The sky camera had been struck by a small rather bright flash between the two exposures, that darker point in the combined image.

A fireball at night, as bright as a full moon

14.9.2018 at 04.06 - Ikaalinen
Jarno Paananen, Tampereen Ursa

The Allsky camera had been left with a bright and apparently rather slow fireball, as it was old in three different 10s exposures, the middle of which ignited. The first image is a combination of those three. Pictured north to left, so the direction of flight has been from northwest to southeast. The timestamp is the end of the exposure. Unfortunately, the camera dome has been a bit dewy, so the stars aren’t visible from all over the field.

A fireball at night, brigter than the venus

Jarno Paananen, Tampereen Ursa

The Allsky camera had captured the ball that went low. I can’t tell the shape whether it was coming or going, but in the picture the direction is southeast.

The tail of the ball had been left in the sky camera, sadly gone out of the box but.

A fireball in a twilight sky

Jouni Raunio, Jarno Paananen, Tampereen Ursa

The newest member of the TaUsra camera family recorded the morning fireball. I was already watching the videos on the NVR right in the morning and I couldn’t find anything but luckily the retest now now with the right time was working.

3122 Florence

1.9.2017 at 23.16 - 23.40 - Tampere (III)
Jarno Paananen, Tampereen Ursa

Despite the clouds, there was little tried and tested asteroid search when this was so heavily advertised. There was a bit of searching when I had to align by hand, but grabbed the edge of the screen nonetheless. The first image is stacked according to the stars and annotated, the movement of the asteroid indicated by an arrow. The other is a GIF animation of just over a hundred squares.

Binocular comet Lovejoy

5.1.2015 at 20.36 - Urjala (III)
Jarno Paananen

A modest comet still saw this during the full moon, but easily recognizable for its color. However, I had to search for images when it was not found on the camera screen and there was only a guess at the direction, so for the sake of certainty, a wider image.

Search result contains observations from time period 1.1.2000 klo 00.00 - 15.8.2022 klo 13.53.
