Airglow: Airglow is a faint emission of light by a planetary atmosphere. In the case of Earth's atmosphere, this optical phenomenon causes the night sky never to be completely dark, even after the effects of starlight and diffused sunlight from the far side are removed. This phenomenon originates with self-illuminated gases and has no relationship with Earth's magnetism or sunspot activity, causing aurorae.

Comet Lemmon and the open cluster Plejades



Another session with clouds and mist. I managed to see Comet Lemmon again between clouds and it was a beautiful view through the binoculars. Behind me the open cluster M45, Plejades, the Seven Sisters was a beautiful sight. At a distance of about 444 light-years, it is among the nearest star clusters to Earth and the nearest Messier object to Earth, being the most obvious star cluster to the naked eye in the night sky

Comet Lemmon getting brighter

I was about to eat dinner and the forecast said mist but I looked out and saw the big dipper clearly. Jumped into the car and went for a quick drive so I had clear view. I could easily see the comet with binoculars but the clouds rolled in. So I took my 300mm lens and made a single expo of the comet before the clouds took over the show.

Comet Lemmon through binoculars




Comet Lemmon (C/2025 A6) is making its closest approach to Earth, only 0.6 AU away. The comet is about as bright as a 4th magnitude star, making it a borderline naked-eye object that looks terrific through small telescopes. The view through binoculars was great!

 Me and my son went for a drive to darker skies to see comet Lemmon a little bit better. But when we arrived a big green bow was visible. We went very fast to put up the gear and photograph and the show just went on. Dring the session we noticed a bow in the south, we thought that it was aurora too but it was actually Surprise: Some Red Auroras are *not* Auroras | Spaceweather.com

A lovely session with comet Lemmon visible too but much more faint because of the Aurora.
