08/25/2015 – Ephemeris – Waiting for more images from New Horizons

Ephemeris for Tuesday, August 25th.  The Sun rises at 6:56.  It’ll be up for 13 hours and 35 minutes, setting at 8:32.   The Moon, 3 days past first quarter, will set at 3:16 tomorrow morning.

The New Horizons team is downloading data now from all the instruments gathered from the encounter with Pluto, but in mid-September the pictures again will be flowing down to Earth.  What was downloaded in the day and a half after close encounter with Pluto were highly compressed images of an area of Pluto and Charon’s surface showing a wider view than we will see later on and in full resolution.  The team is already beginning to name the features that can be seen in sufficient detail.  The International Astronomical Union has decided the types of names for Pluto, Charon and the rest of the Satellites.  Pluto is set aside for explorers, both human and robotic.  Charon, for mythical and fictional space and adventure heroes, vessels and authors.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
