CBET 4754 & MPEC 2020-H06, issued on 2020, April 17, announce the discovery of a comet (magnitude ~15) by Eduardo Pimentel on CCD images taken by Jacques, Pimentel, and J. Barros with a 0.28-m f/2.2 astrograph of the "Southern Observatory for Near Earth Research" (SONEAR) at Oliveira, Brazil. The new comet has been designated P/2020 G1 (Pimentel).
We performed follow-up measurements of this object while it was still on the PCCP webpage.
Stacking of 7 unfiltered exposures, 24 seconds each, obtained remotely on 2020, April 15.4 from Q62 (iTelescope network) through a 0.50-m f/6.8 astrograph + CCD + focal reducer, shows that this object is a comet with a compact coma about 15" in diameter and a tail 20" long in PA 90.
