Today's 2 topics:

- On consecutive nights my Catalina Sky Survey teammate Richard Kowalski discovered two very close approaching asteroids. One of Richard's discoveries, 2016 BY14 must be made out of pretty tough stuff since when it was closest to the Sun it received more than twice the solar energy which heats the surface of Mercury to 800 F. Asteroid hunter's continue to need to track 2016 BY14 to make sure that its orbit does not change to make it a threat as it passes near the paths of Mercury, Venus, Earth, our Moon, Mars, and Jupiter.

- In 2013 my Catalina Sky Survey teammate Steve Larson discovered a space rock streaking through the night sky. For the next 3 days this object was observed by telescopes in California, England, Chile, and New Mexico and given the name 2013 TX68. About 10 days after being discovered, this small asteroid became invisible to human telescopes as it moved towards the Sun with increasing amounts of its dark side facing towards us. Hopefully asteroid hunters will come across 2013 TX68 during its 2016 encounter with Earth. The data obtained will allow us to predict when and how close it will approach our to home planet in future years.
