A bright near-earth-object candidate, reported this morning by
B. A. Skiff, was placed on The NEO Confirmation Page by T. B. Spahr quickly
enough that follow-up observations could be made by J. Young within four hours.
Spahr then located the Oct. 5 observations (which had been reported as a
likely main-belt object) and recognized the object as 1937 UB (Hermes).
With the help of the LINEAR Team, single-night observations (also reported
as likely main-belt objects) could then be identified back to Aug. 26. The
orbital elements provided here have not been linked to the 1937 observations,
since when the object has made almost exactly 31 revolutions. Radar
observations at the present apparition would be very useful.
