Comet 107P/WILSON-HARRINGTON - (= 1949 W1 = 1979 VA)

nger-Brewster

Discovery:

A.G.Wilson and R.G. Harrinton (Palomar Observatory, California USA) discovered this comet on a photographic plate exposed 12 minuites with the 122-cm Schmidt camera on 1949 nov. 19.13 UT. The astronomers estimated the magnitude as 16.  Initially, the comet was reported as having been detected again by Wilson and Harrington on nov 22.16 and nov. 25.13. The magnitude on the former date was estimated as 12.. L.E. Cunningham said the plates esposed on nov. 19 and 22 showed a small, faint tail, but no trace of a coma and “would likely been called a minor planet” had a slower telescope used to expose the plates. He added the orbital period of 2.31 years.

Recovery: IAUC 3423

Eleanor Helin (Palomar Observatory) discovered a fast-moving asteroidal object in Pisces on plates exposed with the 0.46-m Schmidt telescope on 1979 November 15.17 and 15.43. She confirmed the object on the 16th and estimated the magnitude as 11. It received the designation of 1979 VA.

This Apollo-type object has been recovered independently by J. Gibson at Palomar and K. S. Russell at Siding Spring, with the following new observations available.  The indicated correction to the prediction on MPC 14014 (ephemeris on MPC 14032) is Delta(T) = +0.62 day.
