I am on vacation in South East Asia visiting Japan, Taiwan and South Korea.

I did not bring a marine sextant because in these countries it was going to be difficult to get to the shore line with a clear view of the horizon. Also, I did not bring the A-12 bubble sextant neither, because Taiwan and South Korea are in permanent conflict alert against China and North Korea, so it was going to be difficult to explain to the customs authorities at the airports what a sextant was, and even less the A12 that looks like and old film camera. Last year I took the A-12 to Cairo, Egypt and I almost got arrested when taking sights one night on one of the Nile's river bridges. Taking sights with the A12 sextant on the streets of Taipe or Soul is definitely not a good idea. 

Nevertheless, I wanted to practice celestial navigation during the trip and work the sights manually using the nautical almanac and the tables 249, so I used Frank's GPS anti spoof application to take some sights on the streets of Tokyo.Clearly, the objective was not to test the application's precision but rather to practice sight reductions on Eastern longitudes, something that most of us do not regularly do.. In particular, I wanted to get more practice of calculating LHA of Aries, Sun and planets when the assumed position is on Eastern longitude that requires some extra thinking.

To make it easier, I set the application on bubble mode, so I did not have to deal with dip corrections or LL correction for the sun.If anyone in the group wants to have fun and do the manual sight reductions, attached are the screen shots from Frank's application of the Sun, Polaris and Jupiter.
