Ah ???
I thought he would have used :
sin H = sin Lat * sin Dec + cos Lat * cos Dec * cos T , with both Lat and Dec being (adequately) known, then it should (might?) have been straightforward (and hopefully achievable with 10log tables) to reckon Local apparent Time " T " ...
Well ... at least we need a sufficient time between time of height observation and Apparent Noon Time - certainly and least a couple of hours here - simply because we are solving for a Cosine here, and by Apparent Noon time, T = 0 and solving it through its Cosine is not wonderfully accurate.
Am I missing something ?
