NavList:

My plans for today were cancelled, so I was able to make it to the ribbon cutting ceremony for the exhibit.  The exhibit is phenomenal!  The working replicas of H1, H2, and H3 are mind boggling.  I don't see how anybody could have conceived them.  Then again, I don't believe a Boeing 747 can get off the ground, and there is no way video images can be transmitted through the air.

While I was there I stopped at the planetarium and Bruce took me down to the Howell classroom, where I took out a Navy Mark II sextant.  I can now definitively say that it will read to 145º.  The index arm is not blocked by anything, and the index mirror is still not quite perpendicular to the horizon mirror, but darn close, close enough that I would have to believe that keeping a body in view might be difficult.

Subject: [NavList] A Fall of Longitude at Mystic Seaport

The "Ships, Clocks, & Stars" exhibit opened at Mystic Seaport today. This travelling exhibit from the National Maritime Museum, Greenwich, UK includes many unique artifacts and displays connected with the quest for longitude, far beyond the usual re-tellings of the story. Don't miss it.

And of course I'm teaching a bunch of workshops and classes in celestial navigation in its various forms. I'm including here two copies of my digital "flyer" for these classes. Please forward these to anyone you think might be interested.
