Hi all,
Last night I observed again from Frasso Sabino (Observatory 157, Rieti, Italy) the "comet" 2015CD60 and it has not only increased in brightness, compared to December 2nd when I realized it was active, but also the tail is better visible and also longer. Now it should be at maximum brightness (passed perihelion a few days ago and almost at minimum distance from the Earth).
Image data: 40x90s, north at the top and east to the left (north has just rotated about 4 degrees to the left), scale 1".24/pixel and field of 32'.3x21'.6. Date 28/12/2024 mean time 23h30m UT.
Mag. Comet with clear filter 16.8, diameter 11" and tail of 1'.3 in PA289¡ã.
Fun fact: 4 asteroids are also visible in the field (and there are 3 more visible but only by adding their movement).
Regards,
Roberto Haver
