PERIODIC COMET JACKSON-NEUJMIN (1970k)
Mr. Charles T. Kowal, California Institute of Technology,
telegraphs that he has located this comet on plates exposed with the
122-cm Schmidt telescope at Palomar, as follows. The comet is
diffuse, with central condensation and a tail < 1o.

Sept. 6.43855 4 19.9 + 7 21 14
7.43855 4 22.1 + 7 10 14
The comet is about 3' south of the position predicted in the Delta-T
~ -7d search ephemeris on IAUC 2240. The elements and complete
ephemeris are as follows:
T = 1970 Aug. 6.4272 ET Epoch = 1970 Aug. 2.0 ET

PERIODIC COMET BORRELLY (1967 VIII)
Mr. K. Tomita, Tokyo Astronomical Observatory, provides the
following precise positions. The Dec. 8 position was obtained with
the 50/65/100-cm Schmidt at Dodaira; all the others were obtained
with the 188-cm reflector at Okayama.

COMET WHITE-ORTIZ-BOLELLI (1970f)
The Rev. F. W. Gerber, Lucas Gonzalez, Argentina, informs us
that the date of his independent discovery of this comet (cf. IAUC
2251) is incorrect: he first saw the comet on May 23.9, not May
22.9. He informs us also that he learned on May 24 that Alberto
O. Bernhardt, a student of agronomy at Lucas Gonzalez, observed
the narrow tail of the comet on May 22.9.
COMET TAGO-SATO-KOSAKA (1969g)

Bucharest Observatory by C. Cristescu, V. Ionescu and Gh. Bocsa:
