File:Simeis 147.jpg to appear as POTD soon

Hello! This is a note to let the editors of this article know that File:Simeis 147.jpg will be appearing as picture of the day on July 29, 2017. You can view and edit the POTD blurb at Template:POTD/2017-07-29. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. — Chris Woodrich (talk) 05:33, 20 July 2017 (UTC)[reply]

Picture of the day

Simeis 147, also known as the Spaghetti Nebula, is a supernova remnant (SNR) in the Milky Way. Straddling the border between the constellations Auriga and Taurus, the nebula was discovered in 1952 at the Crimean Astrophysical Observatory. It is difficult to observe due to its extremely low brightness.Photograph: Rogelio Bernal Andreo

Galactic Coordinates b=-1.71177 L=180.04204 Error 6.43E-008 Morbas (talk) 08:51, 22 November 2019 (UTC) These coordinates from: Galactic Coordinates{b,l) <=> Equatorial Coordinates{ a , d } sin(d)=sin(dNGP)*sin(b) + cos(dNGP)*cos(b)*cos(lNCP-l) cos(d)*sin( a - aNGP )=cos(b)*sin(lNCP - l) cos( d )*cos(a - aNGP ) = cos( dNGP )*(sin( b )-sin( dNGP )*cos(b)*cos( lNCP – l) Error is found by maneuvering these equations to = 0 and inserting the Galactic Coordinates, then taking the root of the sum of squares = Error.[reply]
