358.51619 9.82608 galactic Oph Second-epoch detections are separated by 0.4" and 6.1 pix
The object was found in VSX15" Gaia DR3 4112708812627568256
Type: E
# Max. Min./Amp. JD0 Period
17.980 G 18.620 G 0.256902000000
NOTE: the measured brightness disagrees with the variable-star record above, but is consistent with the asteroid identification below - so this is likely the asteroid rather than an outburst of the variable.

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!
Don't forget to change the observer code for the AAVSO and VSNET format data!
