PERIODIC COMET MACHHOLZ 2 (1994o)
     Independent reports of a third diffuse object moving with the
same motion as comet 1994o have been received from Petr Pravec
(Ondrejov, 0.65-m reflector) and Wayne Johnson (Anza, CA, 0.56-m
reflector) on CCD images obtained Sept. 2.11 and 3.51 UT,
respectively. Pravec noted a 1'.0 coma with little condensation, the
third companion being located about 43" southwest of the second
object reported by Jaeger (IAUC 6066); Johnson noted this third
component as being about 1 mag fainter than the second.
