B. Skiff, Lowell Observatory, discovered this comet on images taken by him in the course of the LONEOS program, on 17 September 2002 at mag 18.0. The object has a moderately condensed coma of diameter 10" and a tail 30" long in p.a. 285 deg. At Skiff's request, M. Hayes-Gehrke obtained a confirming 5-min CCD R frame (also on Sept. 17, in twilight) with the Lowell Observatory's Perkins 1.8-m telescope, showing a 8" coma and a tail about 30" long in p.a. 280 or 285 deg. G. Sostero, E. Guido, P. Camilleri and E. Prosperi recovered P/Skiff (2002 S1) on 15 June 2009 from the co-addition of forty unfiltered 60-s CCD exposures obtained remotely on June 15.6 UT with the 0.35-m f/7 reflector at the Skylive-Grove Creek Observatory (near Trunkey, NSW, Australia). The comet was 20th magnitude and of stellar appearance. Date 10x10 mag Error Kphot mag Coma ' 04-Sep-18   18.21 0.04 18.2 0.2 30-Sep-18 18.73 0.12 18.7 0.2 10-Oct-18   19.17   0.18   19.2   0.2
