In reply to markryle:
With a strong full moon and a night time inversion on one of your trips did you manage to generate any Brocken spectra’s?
Ive always wonder if it’s possible, is the moon light strong enough. The times I’ve been above inversions at night either the moon phase and/or position has been wrong, or the cloud top too low.
In theory since moon rainbows are possible, and I have seen, albeit in monochrome as our eyes rods and cone cells aren’t sensitive to pick out the colours, it should be possible to generate a Brocken.
But would our eyes see it?
