Very close. Joe figured in half out. There are two green flash phenomenae
(archaic spelling) one at sunset and one at sunrise. The one at sunrise is
more difficult to see but on a good morning not impossible.

Each of those two has a mod 1 version. Mod 1 is navy lingo for
modification. But it doesn't involve airplanes or mast climbing.

The next hint is: A certain, specific weathercondition will give a second
GF at a different altitude both morning and evening. This is the group
where I've managed to see one but the fourth one still eludes.

Climb up and down the mast at sunrise and sunset.

Four types of Green Flash and can, theoretically, be seen at different
times
of the same day as in same daylight hours. Flying North/South is agood
one
but doesn't win any points because you are seeing the same type of GF

and over and over again . . .my friend . . . . A tribute to one of the

Here's the next hint. Two of them are are almost exactly 12 hours apart
from the other two.

Here's a bigger hint. Two of them are at a different altitude from the
other two.

And for Katy . ...never look directly into the sun. Wait until 'most'
of
the orb is below the horizon and only the top ...10% or so remains .
...then
look. The horizon must be clear of haze, sandstorms,
clouds,fogbankswhat
have you AND if you use binoculars which will under those viewing
conditions net you a look each and every time . . .DON't look until most
of
the sun isbelow the horizon. Otherwise, as Katy properly warns, "
