Green Flash Sequence

I got out for sunset tonight and got a nice green flash sequence. The Sun was setting behind a mountain. Look at the right side of the Sun as it sets in the following sequence.

Unfortunately, I got distracted a few minutes later at sunset and missed the potential last green flash (bugs started biting pretty fierce at just the wrong moment).

Again, you can see this from anywhere...half the battle is just showing up and looking.
