Meet Comet, my first sailboat. She's a West Wight Potter 15, a classic design from the 1960s. This example was built in 2003 and is in fantastic condition. This sloop has a cabin with two beds for overnight adventures and her maiden voyage will take place later this month in Patagonia Lake.

This discovery by @wierzchos.bsky.social still looks to be on course to become a nice binocular comet or even more around the turn of the year.

Looking at photographic plates with a loupe is the closet experience to looking through the eyepiece of a telescope. These were obtained by Gerard Kuiper himself.

Achievement unlocked. JWST observed one of my comets. This if from Colin Snodgrass et al. "First JWST spectrum of distant activity in Long Period Comet C/2024 E1 (Wierzchos)" arxiv.org/pdf/2503.14071

Astronomers of Blue Sky, please sign this petition.
The best dark sky in the world - the Atacama Desert in Chile, which hosts many @eso.org telescopes - is under threat from an industrial project. 🔭

World's darkest and clearest skies at risk from industrial megaproject
On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world [1]. The industrial megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies.

Here is the infamous near-Earth asteroid 2024 YR4 from Gemini S acquired with a joint proposal from Catalina Sky Survey (Dr. Wierzchos) and Bryce Bolin. It's currently very faint and approaching magnitude 24. Really pops out with the 8m glass. 🔭🧪

Self portrait at work no. 2. This one is the Bok telescope on Kitt Peak (MPC code V00). May the night be clear because I'm itching to find stuff.

Having fun with Comet for Widows. The last time I used this software I wasn't old enough to vote. I used JPL's absolute magnitude and slope parameter to produce the light curve. Note that comets are notoriously unpredictable and nobody knows if it will reach that magnitude. #CometWatch

The night of May 10th brought a beautiful display of aurora borealis to Tucson and also a new comet. This all sky image was taken at Mt. Lemmon at the time of the discovery sequence of comet C/2024 J2 (Wierzchos). I marked the position of the comet upon discovery with a yellow cross.
