Equinox Sunrise Table in GMT Estimating Approximate Longitude using GMT Sunrise Times on the Spring Equinox These sunrise times are a clue to the Approximate Longitude of each site, except for MC #2 (see note below). Print this page and use with today's Mystery Class GMT Worksheet. This table shows the time the sun rises at each Mystery location on the Spring Equinox. The time shown is NOT the local time. Rather, it is the time in Greenwich, England. This is known as Greenwich Mean Time or "GMT". Why are dates included? NOTE: If the Mystery Class' SUNRISE TIME IN GMT is earlier than the 3/20 sunrise time in Greenwich (06:04 AM), then the location of the Mystery Class will be in the EASTERN HEMISPHERE, east of Greenwich. If the Mystery Class' SUNRISE TIME IN GMT is later than the 3/20 sunrise time in Greenwich, then the location of the Mystery Class will be in the WESTERN HEMISPHERE, west of Greenwich. That is why we have included the dates along with the GMT. Mystery Class Sunrise GMT and Date # 1 16:10 (3/20)   # 2 18:34 (3/19)**   # 3 10:28 (3/20)   # 4 11:12 (3/20)   # 5 20:26 (3/19)   # 6 04:32 (3/20)   # 7 00:17 (3/20)   # 8 05:29 (3/20)   # 9 12:00 (3/20)   # 10 04:05 (3/20) ** MC #2 wants you to know something: "The GMT sunrise time given here is not for our location!; Instead it's for a separate location whose time zone we "borrow". But don't be worried that you won't be able to find a longitude for our location--we've never been able to find one for our location either! Watch the clues in the next five weeks." (Note: The times above are provided in military/24 hour time. Military time is usually expressed without any punctuation. We have used a ":" between the hours and minutes for clarity.)
