彗星 29P/Schwassmann-Wachmann 1 光度测量 (2012-2019)

Presented here is the analysis of photometric observations of comet 29P/Schwassmann-Wachmann 1. Broadband observations were conducted over 15 nights from 2012 to 2019 at the Lisnyky observational station of Taras Shevchenko National University of Kyiv. Apparent magnitudes and dust productivity level $Af\rho$ in the R filter were calculated. The middle and high dust activity of the comet is characterized by the parameter $Af\rho$, which varied from 1246 to 17563 cm during all periods of observation. Based on morphological analysis, four jet-like structures were detected in the coma on almost all dates. Using a geometrical model for interpreting the jet structure across all observation sets, the following results were obtained: a nucleus rotation period of 57±2 days, the rotational axis orientation, and the locations of active regions for the four jet-like structures within a narrow belt near the equator.
