Chapel Hill Astronomical and Observational Society

Mars is visible in the evening sky right now–look Southwest after sunset, low in the sky. The bright star Arcturus will be high in the South, almost straight overhead. Regulus is to the right of Arcturus. Spica is below Arcturus. Contrast the color of Spica (blue) and Mars (red).

Regulus is in the constellation Leo. You should be able to make out the rest of the constellation using the skymap below.

Here is a list of things you should be able to see in the Spring with just ordinary binoculars (7 x 35).

You can use this diagram as a guide. It can be downloaded at The orientation for the map is set for South, with the middle of the circle representing straight overhead. Turn the map upside down when looking North.

The larger the blob on the map, the brighter the object will appear in the sky–note the magnitude legend at the bottom right of the map. Contrary to intuition, the higher the magnitude number, the dimmer the object appears.

Will the ISS make a pass over Chapel Hill tonight?
