Hi, About transits - I like the bit in the film "Longitude" (if I remember it correctly) were Harrison's son is asked by some worthy how they get a local time check. The young lad points to the chimney on a certain house and says that they wait for a particular star to disappear behind it. Assuming that the brickwork was vertical enough and that you had good enough eyesight, it must have been possible to nail it down to the odd second; averaging over several days (long time-constant) would have made it even better. Good enough to find the West Indies anyhow.
Cheers - Joe _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
