Equinox Sunrise Table in GMT
Estimating Approximate Longitude using GMT Sunrise Times
on the Spring Equinox

These sunrise times below are a clue to the Approximate Longitude of each site. 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 March 20, 2006, the Spring Equinox. The time shown is NOT the time of sunrise using the Mystery site's local time. Rather, it gives you the time that it is in Greenwich, England when the sunrise takes place at the specific Mystery Location. This is known as Greenwich Mean Time or "GMT".

"Why are dates included next to the times?"
NOTE: If the Mystery Class' SUNRISE TIME IN GMT is earlier than the 3/20 sunrise in Greenwich (06:03 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 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. A SUNRISE TIME IN GMT that occurs on 3/19 is considered earlier than the 3/20 sunrise in Greenwich.

** MC #6 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.)
