The ‘green flash’ is sometimes observed at sunset, just when the last sliver of the Sun disappears below the horizon. A ground-based observer has only one opportunity per sunset, but –under the right conditions– an airborne observer can repeat the observation two or three times, by gaining altitude, waiting for the Sun to disappear, and then gaining altitude again and trying once more…
I have tried several times with my gyro, but never succeeded in observing that ‘green flash’. In my case, the ‘right conditions’ are a very clear day, and a cloudless mountain horizon 30 km away.
Is there anyone who has tried this observation…?
P.S. I enclose a photograph of that a ‘green flash’, taken from Wikipedia...
