COMET P/2019 LM_4 (PALOMAR)

     An apparently asteroidal object discovered on images taken at Palomar on 2019 June 4 and 7 with the 1.2-m f/2.4 Schmidt telescope (and given the minor-planet designation 2019 LM_4 when published on MPS 1001527, along with observations made elsewhere on June 8) has been re-discovered showing cometary appearance at two other observatories.  The Palomar discovery observations are tabulated below with the reported r-band magnitudes.

B. Li reported the discovery by G. Zhaori of an extended object on images taken by L. F. Hu with the 1.04-m f/1.8 Schmidt telescope at the XuYi Station of Purple Mountain Observatory on May 11 UT in the course of the "Chinese Near Earth Object Survey" (discovery observations tabulated below).  Before the object was posted on the Minor Planet Center's NEOCP webpage, it was discovered independently in images obtained with the Pan-STARRS1 1.8-m Ritchey-Chretien reflector at Haleakala on May 12, with Y. Ramanjooloo (University of Hawaii) reporting that the full-width-at-half-maximum size was

3".6 compared to 1".2 for nearby stars. .....
