Up in the Air is a column written by Dr. Dan Caton, and published monthly, on the second Monday, in the Science section of the Raleigh News and Observer (the Charlotte Observer discontinued the Sci-Tech section after the 4/25/16 issue), and gives information on interesting phenomena seen in the sky.

This web site is in support of that column, and will provide additional links and information about the topic discussed this month.

Further information on this month's column as published online 9/11-12/2016 and in print 9/12:

I have provided below a map of the mid-September sky for about 9:00 pm. Note the Milky Way crossing the evening sky! Of course, the stars appear to move overhead during the night the same way as the sun does during the day–this chart is for about 9 p.m. To use the chart, hold it out in front of you above eye level. Rotate it such that the label for the direction you are facing is down. For example, facing south you want the “South” label at the bottom (as you are seeing it now). The circle represents the horizon, the center of the chart represents the zenith point directly overhead. The CAPITALS are constellation and asterism names. Other names are stars, planets, galaxies or star clusters. The shaded area shows the location of the Milky Way. The Moon is not shown since it changes position nightly. [Art by B. Novo]
