Occultation of Aldebaran
Map of the area where the occultation of Aldebaran will be visible. Created using Occult 4 from IOTA.org.
For Traverse City/Internochen the occultation will start at 8:07 p.m. EST November 5 and end at 9:00 p.m.
It will vary by a few minutes for northern lower Michigan. Otherwise use a planetarium program like Stellarium to preview the event. However, set the program for topocentric coordinates. In Stellarium that’s in the Configuration window, Tools Tab and check the Topocentric coordinates box. Topocentric coordinates are the apparent positions for your location on the Earth. For Cartes du Ciel (Sky Charts) The setting is under Setup/Solar System. So also make sure your location is correct. The geocentric conjunction of the two bodies will be November 6, 2:42.9 UTC, so it will occur after midnight on the morning of November 6th for locations in northern Europe and Asia.
I’ll have more information on November 5th on my blog http://bobmoler.wordpress.com.
