155P / (Shoemaker 3) The periodic comet of the Jupiter family was filmed on the second night of the March work. The comet was discovered on the Near Earth Asteroid Tracking (NEAT) search program on January 10, 1986. The discovery was made by Caroline and Eugene Shoemaker with a 0.46m Schmidt telescope at the Palomar Observatory, source GARY W. KRONK'S COMETOGRAPHY https://cometography.com/pcomets/155p.html . the comet was 1.2404au away, the nearest 1,026au on February 4, 2020. The comet is already moving away and clearly dimmer than when we filmed it in January 2020. In Perihel, the comet has been 15-28 November 2019. The next time the comet will be so well photographed 17 years from now, Outside the orbit of Saturn. 1Picture. stacked Average by comet. A little tail at 7 p.m.
