Jupiter

12.10.2022 at 22.04 - 22.09 - Pieksämäki (IV)
Timo Kantola, Ursa (Itä-Suomi)

Jupiter photographed with a methane filter. On the Internet, I found information that in methane filter images, the uppermost clouds of Jupiter are visible the brightest, and the lower the clouds are, the further you look through the methane-rich atmosphere of Jupiter, at the 890 nm wavelength of the filter, the methane absorbs the light and does not reflect it back into space, that's why. areas darker. Last picture with IRpass filter. The road was very bad.

I looked despairingly at the cloudy sky and nevertheless decided to put the telescope outside to cool down, I also adjusted the tripod to the vatupass to wait until midnight. Around 23:30 I went outside and found that the sky had opened up to starry, placed the telescope on the stand and checked the collimation, and performed the focus. I adjust the object's coordinates and other settings on my telescope and when I'm ready at h-moment 23:55 I press the start icon, after about 1.5 minutes of waiting I saw the star TYC 4709-578-1 covering asteroid 105 Artemis on the screen.

Saturn

Timo Kantola

I dug through my archives and reprocessed this video with the AstroSurface program and got a publishable image of Saturn from January 10, 2009, when the rings were visible almost directly from the side. To the right of the rings there is a dim lightening (thuhnu) which is possibly Tethys moon. AstroSurface AstroSurface AstroSurface

Carpe Diem. Now you have to seize those small moments, when something more than just a gray mass of clouds is available. The copter caught the morning pillar.

Pentti Ketola, Ursa (Länsi-Suomi)

Is there a solar pillar in these pictures, it was ten degrees below zero in Kokkola. An ND8 filter has been used in the wider picture where the clouds are formed as if by a bird's wing.

Taken from an airplane in the morning in the east direction, height at that point approx. 5 km, with a cell phone camera. Could there be pearly clouds or could there still be illuminating night clouds at this time of the year?

Exoplanet HIP 41378f

13.11.2022 at 23.25 - 04.37 - Janakkala, Tervakoski (I)
Petri Kuossari, Riihimäen tähtit. yhdistys

I had the honor of starting to observe the transit of a Saturn-like exoplanet from Tervakoski, Finland, on November 13. It was unusually warm at night +9 degrees and there was a strong storm. I looked for a sheltered spot for my telescope at the end of the horse stable. HIP 41378 f is what astronomers call a "super-puff" planet, meaning it's big, but its density is predicted to be very low. The planet orbits its star every 542 days The planet is of particular interest because scientists believe it may have rings and perhaps even moons, just like Saturn in our own solar system. The Hubble S...

The surprising appearance of the sun and the beautifully wavy color cloud in the middle of the grayness of November made me happy.

(523823) 2015 BG311 (2015 BG311) The asteroid Cupid NEO was imaged on the second night of the 2022 September talcos. The asteroid was discovered by the Haleakala observatory of the Pan-STARRS research program (F51 – Pan-STARRS 1, Haleakala) on November 29, 2014. The estimated size is approx. 740m. At the time of imaging, the asteroid was at a distance of 0.1936au and at its closest on October 15, 2022 at 0.16792au. 1Fig. first image of the series L15s measured, 2022-09-24T 19:29:02UT 2459847.31182JDUT 20h11m37.75s +12d06'19.2" 16.647mag Std Dev 37.255 SNR7.859 FWHM5.576" ,JPL Horizon 20:11...
