The results of photometric observations of comet/steroid 2060 Chiron a
t the Observatorio do Pico dos Dias (Brazil - OPD) and the Observatoir
e de Haute-Provence (France - OHP) during 1994 and 1995 are presented.
The analysis of the data shows a decrease of 2060. Chiron brightness
from its peak values of 1988-1991. The absolute magnitude, H-V, varies
from a maximum of 6.6 in February 1994 up to a minimum of 6.8 in June
1995. Therefore 2060 Chiron is back to a minimum of activity close to
that of 1983-1985. The slope parameter G is found to be G = 0.71 +/-
0.15. It is suggested that the H-G magnitude system, generally adopted
to present 2060 Chiron brightness, is not the most appropriate due to
the cometary activity of this object. Copyright (C) 1996 Elsevier Sci
