Part I: Celestial coordinates and how to use them Here is a list of a few stars with the declination rounded to the nearest degree and right ascension (in hours and minutes): Star name Declination degrees RA Sirius -17 06:45 a Centauri 61 14.40 Rigel 05:14 Capella -46 05.16 Aldebaran +36 0436 Fomalhaut -30 22:56 Vega +38 18:37 Alco +55 Mimosa 50 12:48 Polaris +89 02:31 And a lot of the latitude and longtude coordinates of a few cities on Earth City Toronto, ON Whitehorse.

Circumpolar and non-circumpolar stars: complete the table below, showing which stars are always sometimes, or never above the horizon as seen from which locations. Enter A if the star is always above the horison never sets) as seen from that location, if the star rises and sets, sometimes above and sometimes below the horizon), and it the star is always below the horison never vise from that location (6 pts) Toronto Mumba Manaus Whitehorse Los Angeles Cape Town Punta Arenas Sirius B a Centauri Rigel Capella Aldebaran Fomalhaut Vega Alcor Mimosa Polaris A C 5. On a night when both a Centauri and Mimosa are visible from the same location, which would you expect to rise first?lipti 6.
