You'll want to use the town of Tropic for Bryce Canyon; Torrey is for Capitol Reef which is near the edge of the zone and therefore has a shorter eclipse time. On Tue, Apr 10, 2012 at 7:04 PM, Thomas Sevcik <sfv1ts@hotmail.com> wrote:
Erik, no problem, I can understand the confusion with Great Basin being within a couple of miles of the Utah/Nevada border and the sudden switch between Pacific and Mountain time zones. I got my annularity times from the U.S. Naval Observatory's data services site; http://aa.usno.navy.mil/data/. Under the Eclipses and Transits header, click on the Solar Eclipse Computer. Under "Form A" you'll see the listing for the May eclipse already in the first box. Use the pull-down menu in the box below to click on "Utah." In the last box, the site doesn't recognize national parks, so I used "Torrey" as the city or town which it recognized. Click on "Get data" and a page will come up with the data that I used in my original message. For Great Basin, you'd use "Nevada" as the state, and "Baker" as the city or town. Comparing the two locations, it looks like Great Basin has the edge on the duration of annularity. However, from the Archeological site, we may miss the ending of the eclipse due to the mountains to the west. I will be checking on this factor during my participation at the Annual Spring Star Party there this weekend. Will let everyone on the list know the results early next week. If the snowpack is as low as Jay's message indicates, I'll be hanging around to hike up the trail to the glacier, and hopefully to the peak. Have a good one, and clear skies!
