10/08/2013 – Ephemeris – Comet ISON spotted from Mars
Ephemeris for Tuesday, October 8th. The sun will rise at 7:49. It’ll be up for 11 hours and 20 minutes, setting at 7:09. The moon, 3 days before first quarter, will set at 9:36 this evening.
Tonight look in the southwest at 8 p.m. or so to see the crescent moon to the upper left of Venus. In other news last week Sunday the Mars Reconnaissance Orbiter took photographs of Comet ISON. These have been posted on the Internet. Google ISON Mars. The Satellite’s HiRISE camera wasn’t built for the task, and only revealed a faint blob of light. Earth bound amateur astronomers can do a lot better. The images are posted on the University of Arizona’s web site and are not affected by government shutdown. Any images of the comet from the Curiosity rover will have to wait until the shutdown is over to be posted. Operators of the Opportunity and Curiosity rovers are still at work since ongoing space operations are deemed essential.
Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
