[TowerTalk] Beam headings and sunrise vs sunset grey-line paths

[dw]

Hi All,
At Sunrise the grey-line path in January seems to be traveling NE by ~25
degrees and SW by 205 degrees.
At Sunset its traveling NW by 335 degrees and SE by 140 degrees.

In general great-circle propagation information indicates that the
predominant path from New-England to Japan would represent a beam
bearing of NW 335 degrees.  And at sunset New-England time, I have found
openings into Japan to confirm that.

So what about New-England to Japan at sunrise, which if one follows
grey-line, would seem to indicate that a beam heading of NE 25 degrees
would represent the heading of maximum signal strength following
grey-line at that time of day.

I'm wondering how that plays out....what have you experienced?
Thanks
