Oscar scheduled observations with a 0.4m telescope because he wanted to see the comet's tail.

The observations were made with the 0.4m telescope in Hawaii, using R (red), B (blue) and V (green) filters to make a colour image.

Comet C/2025 K1 has been providing comet observers with lots of excitement as it has been breaking into pieces.  Oscar's observation has been added to the data used for a research paper about the break up https://arxiv.org/pdf/2511.19707  (which also includes data from other Comet Chaser partners/students).

Peter Snowden scheduled observations of Comet 29P for the BAA's Mission 29P campaign.  The observations (lower left) were made with the 2m Faulkes Telescope North in Hawaii.  The comet is very unusual - for information see https://britastro.org/section_information_/comet-section-overview/mission-29p-2 

Richard Miles, who coordinates the BAA's Mission 29P campaign, has analysed the observations.  This is what he says:

"Here are some 2.0-m images depicting this latest outburst thanks to Helen Usher and Peter Snowden, who obtained the first high-res images of the quiescent nucleus (lower frame) taken about 4 days before this weak event. The pre-outburst imaging was scheduled via the Las Cumbres Observatory network on November 8 at the BAA’s Back-to-Basics meeting in Pontefract, UK."  

More details, and further observations, can be can be found on the BAA's Mission 29P campaign website.

This observation of comet/centaur C/2023 RS61 was made by Q for the research team led by Eva Lilley.  Although in the the observation it is actually quite tricky to pick out the comet (!), the researchers can use processing techniques to measure the brightness and the size of the comet's coma (the dust and gas cloud around the comet formed by material coming off the comet).  This is monitored over time to see how the comet is evolving.  Q's observation was added to the data set which is being analysed and will be used in a forthcoming research paper which will include observations with the Hubble and James Webb Space Telescopes.

Eva Lilley sent this message for Q:

Hi Q, this is Eva Lilly, the lead researcher on the active centaur C/2023 RS61. I wanted to thank you for the observations, they are very helpful for my and my team, because they show us this object is now likely persistently active before it passes its closest orbital point from the Sun. Your observations helped us to decide that we will ask for another round of observations with JWST. It turns out this object is very special indeed, it has drifted very fast from the furthest parts of the Kuiper belt beyond Neptune, and it bears traces of the original composition of the protoplanetary disc from which all planets in the Solar system were made, and in extension also the life on Earth, including you and me. It has a lot of interesting organic molecules on it including ammonia and methane, so if we put a piece of it in the room, it would stink like dirty socks and cat pee :-) " 

Chris – scheduled observations of Interstellar Comet 3I.

The observations were made with the 2m Faulkes Telescope in Hawaii on 23.11.2025 at 15:01 UT the exposure time was 30s.  The data will be processed and submitted to Minor Planets Center.
