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)
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, thne taking the root of the sum of squares = Error. degree radian aNGP 192.8594 3.366 dNGP 27.12825 0.473 lNCP 122.93192 2.146 Morbas (talk) 01:31, 23 November 2019 (UTC)
