Triple Conjunction

Article header_simple

This evening, the after Sunset view was beautiful with its celestial triple conjunction of the Moon, and the two planets Mars and Venus. The moon is nearly 49 hours old is easier to spot after Sunset than the one day old new moon. The separation of the Moon and the Sun to the observer perspective in the western horizon is greater, and nearly 25 angular degree apart from the Sun.

Venus was really bright. In term of visual brightness magnitude, the planet Venus was -3.38 which easily outshine the planets Mars which was nearly magnitude of 1.5.

The three celestial made a beautiful evening view. The weather wasn’t as good, and the clouds were coming and the humidity was high. The clouds than were overcast.

The weather was becoming really foggy, and limit the observation, how ever, a couple of close up pictures were take.

One of the things I like to observe usually in the 2nd evening of a new moon, or when the moon is nearly 48 hours of age, is the southern pole region of the moon from earths perspective. The crescent at some point due to the geological features of the Moon just disappear, as if the crescent has a hole. The look of the crescent is captured well in the next photo.

From this location of the globe in southern California, the winter crescent new Moon shine brightly over the valleys and plains . The western horizon after sunset featured a beautiful 25 hour old of age thin crescent Moon.

Another notable celestial object near by was the planet Venus, and next to it very dimly at this time of the day, the planet Mars next to it.

The weather felt humid, and there was a fog thin mist. The weather was getting cloudier, and the weather forecast predict to for a cloudy weekend. The temperature was dropping, after a day near the 26 Celsius degree rang (80~75F degree).

The Moon was a little more than 24 hours old from it’s last new Moon event where the Sun rays cast over the moon shift location from earth perspective. The Moon had ~1% luminosity, phase .1 .

Tomorrow, I am hopping for a better weather than what is predicted, or at least few clear windows between the clouds in the western horizon to see the crescent moon near the planets Venus and Mars.

Here is another photo with less exposure time where a glimpse of the lunar geological features  can be noted even with an unaided eye.
