Third October Comet is in the Skies

[SorellaLaBefana]

However, like the other two Autumnal Comets, will likely be only visible to those with binoculars, telescopes and a certainly level of night sky savvy.

Comet Lemmon is brightening and moving into morning northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures.

Comet Lemmon was discovered early this year and is still headed into the inner Solar System. The comet will round the Sun on November 8, but first it will pass its nearest to the Earth -- at about half the Earth-Sun distance -- on October 21. Although the brightnesses of comets are notoriously hard to predict, optimistic estimates have Comet Lemmon then becoming visible to the unaided eye.

The comet should be best seen in predawn skies until mid-October, when it also becomes visible in evening skies...

Hopefully NASA APOD will continue to be a guide. Astronomy Picture Of the Day remained up during the last tRump shutdown which lasted over a month in 2018-2019, as did the site when Republicans shut down the government for about two weeks in 2013. One can hope.

Here's a link to a skymap site which is current and *fairly* straightforward to use https://theskylive.com/planetarium

After setting your location, click on the Magnifying Glass icon on the left of the bottom menu and enter the name of the comet you are searching for. The three October Comets are:

Comet C/2025 A6 (Lemmon)
Comet C/2025 R2 (SWAN)
Comet C/2025 Kl (ATLAS)
