after an object, newly listed on the PCCP, I observed this with a 0.61-m f/6.5 telescope from Telescope.Live in Chile, and could possibly be a comet because of a small elongated coma of 9 arcsec. After this was reported to the minorplanetcenter and other observations, this object was catalogued as a comet as C/2021 T4 (LEMMON) via MPEC 2021-U187 issued on oct. 28
