October Moon Phases Chart and Cold Air Effects

http://www.moonconnection.com/moon_phases_calendar.phtml
Above is the calendar of the moon phases for the month of October.

Something interesting to note is how the colder air effects the stargazing experience. Light pollution and air pollution both effect our ability to see the stars above. The effects of this are more prominent during the winter as cold air is more dense than hot air. Because of this, light sources appear more bright in cold than in warm air.

This plays out in two ways. The the first sense, light pollution is a bigger concern as the air gets cooler. On the other side, the cool air means the starlight will appear brighter to us here on earth. If you have wondered if the stars are brighter in the winter, you are right. Well, they are least appear to be brighter.

Get ready to bust out some sweatshirts because some of the best stargazing times are now upon us!
