Online MPChecker may fail to identify bright comets! Please manually check the Seiichi Yoshida's and Gideon van Buitenen's pages.
Don't forget to copy the leading white spaces and change the observatory code!
The code 'C32' is 'Ka-Dar Observatory, TAU Station, Nizhny Arkhyz', the code '500' is the geocenter.
Make sure there are no trailing white spaces after the observatory code.
The string should be exactly 80 characters long to conform to the MPC format.

You may copy/paste the above measurements to the following online services: MPChecker (in case the button does not work) NEOCMTChecker (NEO's and comets) sat_id2 (artificial satellites; needs at least two observations to work) fitsblink_satellites (art. sat.; you'll need to save the astrometry as a text file and upload it)
Here is a stub line for reporting a new transient to the TOCP.
Don't forget to set the constellation name and the number of days since the last non-detection!

All-image limiting magnitude estimate: 14.1 (SNR ) 11.4 (80% of stars) with default.sex.telephoto_lens_onlybrightstars_v1
The first estimate is the magnitude of a star detected with a signal-to-noise ratio of following Karpov (2025, Acta Polytechnica, 65, 50).
This value should be representative of the faintest stars clearly visible in the image.
The brighter of the limiting magnitude estimates for the two second-epoch images is reported here.
The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
This value is representative of the faintest object that may enter the candidate transients list.
The hard cut-off for the candidate transients is 15.0 mag.

All-image limiting magnitude estimate: 14.2 (SNR ) 13.6 (80% of stars) with default.sex.telephoto_lens_vSTL
The first estimate is the magnitude of a star detected with a signal-to-noise ratio of following Karpov (2025, Acta Polytechnica, 65, 50).
This value should be representative of the faintest stars clearly visible in the image.
The brighter of the limiting magnitude estimates for the two second-epoch images is reported here.
The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
This value is representative of the faintest object that may enter the candidate transients list.
The hard cut-off for the candidate transients is 15.0 mag.

Estimated accuracy of the plate solution: 2.10"
ITERATION 02 -- talking to VizieR, this might be slow!
UCAC5 search strategy: trying local copy first
Found a local copy of UCAC5
Reading UCAC5 zone files...
Searching UCAC5 zones 332 to 389 (Dec -23.5 to -12.5)
Done reading UCAC5 zone files...
Matched 691 stars with the local copy of UCAC5.
The local UCAC5 search seems to be a success
Accuracy estimation diagnostic: 685 matched stars entering correct_measured_positions(), 20146 with non-zero local correction accuracy
Estimated accuracy of the plate solution: 2.06"
Accuracy estimation diagnostic: 685 matched stars entering correct_measured_positions(), 21169 with non-zero local correction accuracy
Estimated accuracy of the plate solution: 1.17"
Excluding outliers - 685 stars left (next iteration limit 705)
Stop iterations.
