Jupiter approaches opposition

21.9. Jupiter is in opposition on 26 September, i.e. directly behind the Earth as seen from the Sun. In opposition, the planet is at its brightest. In the case of Jupiter, oppositions occur every 13 months, and this time the planet is closest to Earth for more than half a century. The picture was taken by Lasse Ekblom in a good seeing window on August 26.

A lone anthelion in Kaarina

18.9. In the morning of 17.9. Hannu Lahtonen was paying attention when he managed to spot a solitary anthelion in the mixed-cloud sky in Kaarina. The phenomenon, when it occurs at low sun elevantion range, is actually part of the diffuse anthelic arc, its brightest core. In a typical situation anthelion is a part of a complex halo display, but Lahtonen does not mention that other halos were in the sky in this case.

The disintegration of Monday's fireball on video

16.9. Several eyewitnesses recounted the Monday evening fireball on 12. September having split into two or three parts. The disintegration was also recorded in the images of the Nyrölä meteor camera. Harri Kiiskinen published a video showing how the fireball gives birth to a dimmer, shortlived fragment. Kiiskinen says that the fireball is visible in the camera images for 11 seconds, but says that the actual flight was longer because the beginning was not recorded on the camera.

Plenty of observations from Monday night's fireball

13.9 . The observatory has already received 59 observations on September 12. from the fireball seen at 21:42. The observations are focused on the southwestern corner of Finland. Several reports say that the fireball split into two or three parts, with estimates of the duration of the phenomenon being mainly around 5-7 seconds. In the photo, the observation of the fireball by the camera of Ursa Kevola observatory in Turku.

Ismo Pyhtilä

I was in the birdwatching tower watching birds and looking straight up at the sky I caught a halo. At first it was dimly visible, after which the colors intensified and the halo became more clearly visible.

The bridge over the sunspot. Area AR3105. I've seen these bridges before, but haven't managed to photograph them. I'm not sure if it counts as two commas or one, with a bridge going over it. Two large filaments also stand out in the picture. The overexposed spot above the colon is apparently a small blur. The color doesn't quite match the one seen in the eyepiece, it should be redder, but when edited this way, the bridge and the penumbra around the little one can be seen better. The first successful image with the new self-assembled tube: Lunt 80 standard + Skywatcher 150 refra...

We spent an open-door evening at our Meteorii in Söderfjärden. Its aim this time is to crown the evening flight of approx. 9,000 people to the sea to spend the night. Fittingly, the direction was towards the sun pillar. More bird photos as a bonus.

A fireball at night, brighter than the venus

Kalle Luotola, Porin Karhunvartijat

I tried to photograph the heart fog and the soul fog, and in that noise, this fireball, possibly the Perseid, was recorded on the camera. I didn't see this particular fireball, but an interesting looking one fading and brightening again. The fix: Probably a satellite or some other man-made space debris. I checked the clock on the camera and it advances for about 3 minutes. It would be interesting if that Viiru cause could survive.

A fireball at night, brighter than a full moon

23.9.2022 at 01.02 - Jyväskylä (III)
Vesa Vasankari, Ursa (Länsi-Suomi)

For a change, the sensor of my own surveillance camera had also detected movement in the night sky. It just seems that the event has to be spectacular enough to be registered. In the first clip, there is a bang recorded after the barking of the dogs, which must be assumed to be caused by the explosion of the fireball. A really spectacular display of the southern sky!

A bright ball of fire flew towards the east and suddenly extinguished, looking spectacular. It was visible from behind the cloud net and I added a few videos.

M31 as observed from the Pori Bear Guard Observatory. A bright, approx. 95% low moon prevented M31 from being observed with the naked eye. Light wind, thin clouds and light fog in low and open areas. A picture of the conditions as well.
