For the past month or so Comet Catalina (C/2013 US 10) has been moving in a northeast direction across my morning skies. It has hovered at around 6th or 7th magnitude making it somewhat visible in binoculars and obviously visible with telescopes. Sadly with my meager photo equipment this comet has so far eluded my efforts. There are some spectacular pictures showing a comet with a greenish tinge and two tails. However that is not the point of this posting.
Over the next several mornings the comet will pass by the reddish star Arcturus in the constellation Bootes the Herdsman. To many the star pattern for this constellation resembles a kite shape and Arcturus is at the bottom of the kite where the kite tail is attached. The animated graphic shows the comet in motion for December 31st and January 1st.
The morning sky, in addition to the comet – Arcturus pair, also contains two other pairs, or conjunctions. Jupiter has the Moon for a one-day partner and further east toward the horizon is Mars and the bluish star Spica in Virgo.
