dc.description.abstract	The results of photometric measurements (in UBV filters) of Comet P/Halley during four nights in January 1986 have been presented. Rapid recurring increases of P/Halley's brightness were observed during these four nights. This phenomenon seemed to occur at a time interval of about 23.7±0.3 hr. The maximum variation of brightness during an individual night amounts to ΔV~0.ᵐ66 in U, B, and V filters, respectively. Rapid irregular short-lived fluctuations of brightness of the order of 0.ᵐ1 were also found present during an individual night. The present observations show the active nature of P/Halley.	en_US
