I took pictures on Saturday and Sunday night of the Sun setting behind Kitt Peak. Lots of little green flashes. Saturday night was particularly spectacular as the green flashes jumped out naked eye (I use a cable release to take the pics so I can watch sunset and photograph at the same time!).
Here is a gallery of Saturday and Sunday night pics. Click any of them for a larger view. The last four are from Sunday night. Look for a couple of mock mirage flashes at the top of the Sun (the little piece that appears to have broken away from the Sun).
The Sun is setting south of Kitt Peak now and I really can't get home from work in time to photograph sunset, so I am pretty much confined to weekend pics now until next spring. I am already looking forward to early February when the Sun will set behind Kitt Peak on its journey north.
