Leo, the Moon, Mars, Mercury, and a Ram

   No, that is not the opening line to a “walked into a bar…” joke, but rather an example of trying to fit 4 different topics into one title!
Read on.

   Friday evening January 29th the 17-day old waning gibbous Moon will be about 4-5o from the star Regulus. This star is known as the ‘Heart’ of the constellation Leo the Lion.

   Mars is visible further west over the southwest horizon and is a few degrees from the planet Uranus. Both are near the 3-star pattern for the constellation Aries the Ram and its brightest star Hamal with a 2.0 apparent magnitude. The two planets have a sharp contrast in relative apparent magnitude with Hamal and with each other – Mars at 0.40 and Uranus at a 5.80 apparent magnitude. Both planets will fit within the field of view of binoculars with Mars appearing as a small reddish ‘dot’ and Uranus, if seen at all, a much fainter bluish-green and smaller ‘dot’.

   Earlier in the evening, after sunset, look toward the western horizon for the innermost planet Mercury. With an apparent magnitude of 0.45 Mercury is slightly dimmer than Mars and should be easy to spot as it will be the brightest star-like object in that direction.
