Comet Catalina (C/2013 US10) is a comet discovered in 2013 and is expected to give a beautiful show from observers on planet earth perspective on the months of December 2015 and January 2016.
Comet C/2013 US10 is a morning comet, and the observation took place in the early hours of dawn toward the eastern horizon.
Observation of this comet from California was a bit difficult due to the weather condition and the brightness of the Comet. Comet Catalina was expected to be a naked eye comet, how ever, the comet didn’t reach the magnitude 4 in the scale of apparent brightness as was expected. Today, when these pictures were taken, the apparent magnitude was about 6~7 and many low clouds near the eastern horizon had played a role in making the observations more challenging.This morning the comet made a small conjunction with the Moon crescent and the planet Venus as shown in the pictures. The comet is too dim to be observed with the naked eye, but the view is beautiful with telescopic aids or a camera.
Here is a couple of close up pictures of the comet where the comet was marked in the picture:The brightness of the morning dawn before Sunrise was taken over, and making the background sky brighter than the Comet. However, more pictures was manged to be taken.
The Moon and Venus made a beautiful display by them self.I hope the weather will be more cooperative in the next few days and that the comet will have a good display show for it’s observers this season.
As for now, here is more pictures of the Moon, Venus, and the comet, with the dawn glare in the back.
The observation took place between 2 hours and an hour before Sunrise.
Wind were around 4~9 mile per hour (7 to 14 KPH) and the temperature didn’t exceeded 66F (~18C degree) and was in the low 50F degrees at some point.Santa Susana Pass, Los Angeles county
