Comet 41P / Tuttle-Giacombini-Kresak and NGC3198
in the Evening sky
March 14, 2017

 
 A
            bright 7th magnitude tailess comet passes a stunning inclined
            spiral last night! The 10.5 magnitude spiral on the upper left
            is about 8 arc minutes wide and reveals fine details including
            many blue or pink knots in the spiral arms, and a yellow core.
            The comet is more yellow in hue on the right side of the coma,
            and appears to have a short tail like extension going in that
            same direction.
