Messier 63 (also known as M63, NGC 5055, or the Sunflower Galaxy) is a spiral galaxy in the constellation Canes Venatici consisting of a central disc surrounded by many short spiral arm segments. M63 is part of the M51 Group, a group of galaxies that also includes M51 (the ‘Whirlpool Galaxy’). M63 is an active galaxy with a LINER nucleus.[3]

M63 was discovered by Pierre Méchain on June 14, 1779.[4] The galaxy was then listed by Charles Messier as object 63 in the Messier Catalogue.

In the mid-19th century, Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.[4]

In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63.

Tennessee Spring Star Party at Dusk

Tennessee Spring Star Party at Dusk

Sat Night had some thin clouds moving through

Sat Night had some thin clouds moving through

 

Friday night was fantastic without a cloud to be seen.  Saturday night was less pristine with a lot of thin cloud moving through.  I thought we had some clearing later but a lot of the images from Sat night showed very inconsistent background values which leads me to believe we had thin stuff moving through all night.  Still, how many clear nights can you ask for?  It was a great TSSP and looking forward to the Fall Star Party.

SQM measurements topped out around 21.3 on Friday night and 21.4 on Saturday night.
