Astronomy question
#1
Hi;

I need help with this one if anybody is versed in astronomy.

Duffy's idea is that when he gets a certain bit of information, the position of the sun and moon at that time are significant.

If within 30 days a mag 5+ quake happens, the sunrise/sunset curve will be passing thru one of those points.

Now I can compute the subsolar and sublunar points and I can compute sunrise/sunset times for the quakes but I can't compute the curve representing all the places on earth where they're rising or setting.

I can compute the distance between two points on earth so can I say if sunrise is the right time and it's 90 degrees from a certain location that the curve falls thru that location?

I think so but I'm not sure.

Roger
