Comet C/2025 R3 (PanSTARRS) is now putting on a show, visible low in the predawn sky, with binoculars or telescope.

You can use this website to see the location and elevation angle of the comet from your location and predawn time.
E.g., the view below is at 6:00 a.m. local time April 14 in NYC. Elevation angle = 24°
Stellarium tracks it for me.

Comet R3 (PanSTARRS) featured on NASA APOD yesterday.
This beautiful image of the comet sporting a tail extending over 10 degrees, was taken on April 9 from Sion, Switzerland with the big mountain Bietschhorn on the left.
The composite image was taken with a 120-300 lens, set at 180mm.

5/nComet C/2025 R3 (PanSTARRS) is featured in today's NASA APOD.
This image was taken by astrophotographer Haythem Hamdi, in Rhode Island, USA, on April 12. It captures the comet’s glowing coma and flowing tail shaped by the solar wind. Haythem used an Askar 80PHQ refractor and reducer to get a wide field of view for framing the long tail.

11/nLooks like Comet C/2025 R3 (PanSTARRS) survived its trip around the Sun and is now on its return trip out of the Solar System.
The comet makes its closest approach to Earth today.
These are images captured by the ESA/NASA Solar and Heliospheric Observatory (SOHO) LASCO C3 instrument.
LASCO = Large Angle and Spectrometric COronagraph.

12/nThe ESA/NASA Solar and Heliospheric Observatory (SOHO), launched on Dec. 2, 1995, has been studying the Sun for over 30 years, from its perch in a Halo orbit around the Sun-Earth Lagrange point L1.
With its 12 instruments, SOHO allows scientists to study the Sun’s internal structure and dynamics, the chromosphere, the corona, and solar particles. It has discovered over 5,000 comets.

13/nThe horror! The horror!
How billionaires, one in particular, are destroying the night sky and astronomy.
This is a pic of Comet C/2025 R3 (PanSTARRS), trapped in a celestial cage of light streaks formed by LEO satellites racing across the sky in this 10-minute exposure image.
This is with ~10,000 orbiting satellites. Now, imagine a million of them, each with a solar array ~10x larger.

14/n@AkaSci that is a great and saddening picture.
I love seeing people’s long exposure pictures of the night sky. Seems like those sort of images are going to become a thing of the past.
Although I am sure some AI company will offer a tool to strip the satellite tracks away. Thus annoying me a little bit more.
