Astrometric and photometric observations of comet 29P/Schwassmann--Wachmann 1 at the Sanglokh international astronomical observatory

TL;DR

This study presents astrometric and photometric observations of comet 29P/Schwassmann-Wachmann 1, analyzing its orbit, brightness, color indices, and nucleus size during a period of increased activity in 2017.

Contribution

It provides new observational data on comet 29P/Schwassmann-Wachmann 1, including orbit calculation, brightness measurements, and nucleus estimation during an active phase.

Findings

Determined the comet's orbit and coordinates.

Measured apparent and absolute magnitudes in BVRI bands.

Estimated the nucleus diameter.

Abstract

Astrometric and photometric observations of the comet 29P/Schwassmann-Wachmann 1 were performed at the Zeiss-1000 telescope of the International Astronomical Observatory Sanglokh (IAOS) of the Institute of Astrophysics, Academy of Sciences of the Republic of Tajikistan in July and August 2017. Although the comet has a short period of revolution it is regarded to be an object of the Centaurs group. Comet was exhibited a new activity this period which we used for analysis of its features. The coordinates of comet were determined and the orbit was calculated, the apparent and absolute magnitudes in BVRI bands were determined, as well the comet color indices and the estimation of nucleus diameter were obtained.
