A new comet discovered with the Schmidt telescope at Calar Alto
"
"In the framework of the Space Safety program of the European Space Agency (ESA), Rainer Kresken, an ESA engineer observing remotely with the Calar Alto Schmidt telescope, reported in December 2025 the discovery of a new comet, P/2025 W3 (Kresken). .."

Just woke up from a crazy #night observing #HIP41378 with so many instruments. Quick updated status (from what I just red):
- photometry: so far it seems only @hubble86 got a good weather during the expected ingress 🤞
- spectroscopy: data from #CARMENES / #CalarAlto, #HARPS-N / #TNG & #ESPRESSO / #ESO are in my mailbox. ✅
No news yet from the US-based observatories (and India who haven't started observing yet).
We are still IN TRANSIT.
Good news ! after some fear because of strong wind, @JuliaVSeidel, is currently observing #HIP41378 with #ESPRESSO / #ESO-#VLT. Below is the view of the star (in orange) in the VLT focal plane entering the fiber feeding the light to the spectrograph.
I also got good news from #CalarAlto where they managed to observe the target under very good and stable #conditions.
I am not aware of a transit detection in photometry over Europe yet. Weather wasn't great for photometry.
The night is getting to its end over #Europe. Here is the status of the #HIP41378 f campaign so far:
- #HauteProvence observatory: we got ONE (likely out-of-transit) spectrum through a hole in the clouds
- #CalarAlto: all-sky camera showed stars all the night. I've not heard back from the observatory yet, but it looks good
- #LaPalma had lot of cirrus passing. Likely a killer for photometry, but OK for spectroscopy. 🤞
Now, it's time for #ESO to start the show !
