COMET C/2023 U1 (Fuls)
D. Fuls reports the discovery of a comet in survey images taken by
Mt. Lemmon Survey (G96) on Oct. 16 UT, noting a condensed 8".8 coma and
a broad 6".4 tail at position angle 345 deg. H. Sato reports a very
condensed 10" coma observed on Oct. 16 UT in 12-stacked 60-seccond exposures
from iTelescope Observatory (Q62).
