The equation of time is 8m 00s. The mean Sun is ahead of the apparent Sun. If you are 2°W of the central meridian of your time zone, when will the apparent Sun cross your meridian?

The equation of time is 8m 00s. The mean Sun is ahead of the apparent Sun. If you are 2&deg;W of the central meridian of your time zone, when will the apparent Sun cross your meridian?

Accepted Answer

Option C: 1216. Per Bowditch, apparent solar time equals mean solar time plus the equation of time when the mean Sun is ahead (8m added). Adjusting for the 2¼irc difference from the central meridian (4 minutes per degree, so 8 minutes subtracted for being west), the apparent Sun crosses at 1216.
