Stan... ask three different sources, get three different answers. ;-) From my east valley location I get the following: Sky Tools 2 says 16:29 Megastar 5 says 16:17 Starry Night Pro 5 says 16:22 Peter ----- Original Message ----- From: "Stan Gorodenski" <stan_gorodenski@xxxxxxxxxxxxx> To: "AZ-Observing" <az-observing@xxxxxxxxxxxxx> Sent: Friday, March 02, 2007 5:16 AM Subject: [AZ-Observing] Polaris Transit My sky program gives a transit time of Polaris for today, March 2, of 16h 27m Mountain Standard Time. To check if the sky program I have is computing this correctly, would someone be able to verify this with the program they have? I am using Guide, ver. 8. At one time the "The Astronomical Almanac" published Polaris transit times, but they dropped that and in its place is the transit time of the Sun. I have verified the Guide program is computing the transit time of the Sun correctly, assuming the Almanac time is correct. However, unless I by hand compute the Polaris times from the Sun times (it is easy to make a mistake doing this), I have no way of knowing if Guide is computing the correct value.
