Dr. M. Huruhata has cabled a correction to the elements by K.
Hurukawa given on IAUC 2284: Incl. should read 61o.31, but the
corresponding correction to the ephemeris is not more than 2'. Dr.
Hurukawa notes in addition that the elements were based on the
three positions of Oct. 20.41120, 21.41323 and 22.41337, seven
other positions yielding residuals of less than 5".
OCCULTATION OF PALLAS BY THE MOON
A communication received via the U.S. Naval Observatory from
A. M. Sinzi, Hydrographic Department, Tokyo, indicates that the
4.3-day old moon will occult (2) Pallas (mpg = 10.3) on 1971
January 1. The phenomenon will be visible generally in the Middle East
and the southwestern USSR. At Abastumani there will be a near
graze. Other local circumstances (UT) are:

PERIODIC COMET ENCKE (1970l)
Dr. R. L. Waterfield, Woolston Observatory, sends the following
precise position, measured by him from a plate exposed by
R. H. S. South and himself. The 80-minute exposure showed the
comet as a circular central condensation 20" in diameter, with an
extremely faint, diffuse outer coma about 1'.5 in diameter.

Oct. 21.84832 0 28 15.30 +30 14 12.6 14.5
Dr. S. van den Bergh, David Dunlap Observatory, reports that
he observed this comet accidentally with the 122-cm Palomar Schmidt
telescope on October 4 when the comet was near the field of M 33.
The comet, of magnitude about 17, had a stellar nucleus and a very
faint coma.
