     Total magnitude estimates (cf. IAUC 5993):  June 9.43 UT, 11.7
(A. Hale, near Orogrande, NM, 0.41-m reflector, visual); July 3.72,
12.3 (A. Nakamura, Kuma, Shikoku, Japan, 0.60-m reflector +
unfiltered CCD); 15.72, 12.0 (Nakamura).


PERIODIC COMET MACHHOLZ 2 (1994o)
     The primary component of this comet has evidently brightened
since discovery.  P. Pravec reports that 120-s CCD images taken
through a 2' aperture by M. Wolf and L. Sarounova with the Ondrejov
0.65-m reflector (+ V filter) shows that the total brightness was
about 2-3 mag brighter on Aug. 23.07 UT than on Aug. 15.92 and 16.90.
     Total visual magnitude estimates (cf. IAUC 6057):  Aug. 19.07
UT, 8.2 (L. Szentasko, Veresegyhaz, Hungary, 0.33-m reflector);
23.09, 7.8 (J. Lancashire, Cambridge, England, 10x80 binoculars);
28.12, 8.6 (H. Mikuz, Ljubljana, Slovenia, 0.20-m f/2 Baker-Schmidt
camera + V filter + ST-6 CCD); 28.36, 7.7 (J. E. Bortle, Stormville,
NY, 20x80 binoculars); 30.36, 7.6 (Bortle).
