Hi there: Yes, the boxes for W and E of Greenwich are apparently 'merged' a little, though the times for the Greenwich meridian and Lat 52 degs seem the same whether E or W is specified However, times of transit of the sun on 28th August 2003 at Greenwich and at Lat 52 degs are given as 13:01:21 but WinEphem gives it as 13:03. I am not sure which is correct. (For ref: times for East (given as 07:32:36) are 07:34:10 on WinEphem and times for West (given as 18:30:37) are 18:31:51 on WinEphem. I suspect in the case of the East/west figures that refraction (which is approximated in WinEphem) might not be being considered in your package - though I suspect that one needs to take it into account at such extremes. However if so, why does the time of transit differ by one and a half mins? Patrick -
