... An estimate the rotation period of cometary nuclei is important for understanding and describing the physical processes of the cometary activity. Unfortunately, the measurements of the rotation periods of the comet nucleus depend on the model assumptions and it is one of the main reasons for the scatter of the estimates given in various articles for a given comet. ... Right: the image of the comet 29P/Schwassmann-Wachmann 1 obtained at the 6-m telescope. ...
