CommentFirst observed Comet Holmes. Impressed! Round, very bright with binoculars 7x50. The central brighter part of a diameter of about 2-3', peripheral diameter 11', slightly fainter. Star comparison of Perseus and Cassiopeia, mag of the comet is 2,6 m. While the comet is not going to surrender their positions!
