Night Sky Observations (Color of Stars)

On Saturday, June 16, 2012, I went outside and looked at the stars.  I went outside around 9:45 PM and I saw ten different stars.  For the thirty minutes that I was outside, I did not see the moon at all. I used an app on my boyfriend's phone, Google Sky Map, to classify which stars were which.

The first star that I saw was at 9:53, and it was Polaris.  Polaris was the easiest star to find, and I thought that it looked blue-white.  The second star that I saw was at 9:58, and it was Dabhe.  I thought that it looked yellow-white as well.  I saw the third star at 9:59, and it was Merak.  I thought that it looked light yellow.  Entamin was the fourth star that I saw, at 10:01, and it looked light red.  The fifth star was Aldermin.  When I saw it at 10:03, it looked light blue.

The sixth star that I saw was at 10:05, and it was Phad.  I thought that it was looking more white.  The seventh star that I saw, Caph, was at 10:07.  I thought that this star looked yellow-white.  I saw the eighth star, Capella, at 10:09.  The ninth star that I saw, Alnath, was at 10:13.  This star looked blue-white to me.  The last star that I star was at 10:16.  The last star was Alkaid, and I thought that it looked blue.

The stars that were the brightest were the yellow and white ones.  I feel like these were the brightest, because they have a lot of mass and fuel to burn.

The stars that were the hardest to see was the orange and red ones.  I feel like these were the hardest to see, because to me, all of the stars looked more on the whiteish and yellowish side.

The star that was the least brightest was the Phad.

  2. Capella was not visible on the night of your observation. A lot of the stars you choose were fainter where color wouldn't be apparent. Why not choose the brighter easier ones? It counts as an observation with errors.
