I imaged this comet last night 20241126_27. I used the MPC ephemeris in Astrometrica to measure with. My astrometry as submitted to MPC last night is attached. I hope this helps.

From: t.lehmann@... To: [email protected] Cc: mrudenko@... Sent: Wednesday, November 27th 2024, 18:34 Subject: [comets-ml] 333P - MPC coordinates far off I am currently doing some work on older images and noticed a large difference in coordinates of 333P between MPC and JPL. While the latter are very close to the position of the comet in the image the former are off by almost 1 degree. In addition to the wrong position the web form does return a completely wrong motion vector as well. Could anybody check this? Thanks Thomas |
