COMET HARTLEY (1982b)
     K. S. Russell, U.K. Schmidt Telescope Unit, telexes that Marc
Hartley has discovered a comet on exposures with the 1.2-m Schmidt
telescope at Siding Spring.  Russell's measurements yield:

     1982 UT             R. A. (1950) Decl.         m1
     Feb.  5.73327    12 29 20.14   - 6 46 19.4    ~14
           6.75184    12 32 09.67   - 7 13 17.2


COMET HARTLEY (1982c)
     Russell also provides measurements of a second comet,
discovered by Hartley on the same exposures:

     1982 UT             R. A. (1950) Decl.         m1
     Feb.  5.73327    12 31 58.81   - 7 04 10.1    ~17
           6.75184    12 34 51.53   - 7 31 24.4

Nothing is reported about the appearance of either comet.  Russell
notes the remarkable similarity of the motions of the two objects
and suggests that they may be genetically related.


PERIODIC COMET SCHWASSMANN-WACHMANN 1
     Further total magnitude estimates: Jan. 27.40 UT, 12.3 (C. S.
Morris, Harvard, MA, 0.25-m reflector; visual); 27.96, 13.5 (A.
Parravano, I. Ferrin and E. Guzman, Merida, Venezuela; photographic;
fan-like coma); 29.37, 12.5 (Morris); Feb. 2.37, 12.8 (Morris).


NOVA AQUILAE 1982
     J. Mattei, American Association of Variable Star Observers,
informs us that an independent visual discovery of this object was
apparently made on Jan. 28.5 UT by K. Beckmann, Union, MO, but bad
weather prevented confirmation.  The visual magnitude estimates by
J. Morgan, Prescott, AZ (cf. IAUC 3661), have been revised (using
reference stars SAO 124563 and 124601) and extended as follows: Jan.
29.6 UT, 7.1; 30.6, 7.4; Feb. 1.5, 8.0; 2.6, 8.2; 3.6, 8.6; 5.5,
9.1.  P. Collins, Cambridge, MA, has made the following additional
visual magnitude estimates: Feb. 2.5 UT, 8.4; 5.5, 9.4; 7.4, 9.5.
