Hi Tom. I agree completely with Bernard. Very interesting! I have tried to shoot the solar green flash at sunset on the Pacific coast and from atop Kitt Peak. No luck on any of my tries. There is a restaurant in Pacific Beach (San Diego) California on the ocean called "The Green Flash" with lots of green flash pictures on the walls... Maybe others on this list have been there? Good work Tom! Thanks, Howard Bernard Miller wrote: >Tom, > >I didn't even know this was possible.
