Wolfgang and I spend New Year's Eve 2 years ago on the top of the Wendelstein Mountain. 100m lower down was the "Wendelsteinhaus" tavern with a party in full swing. After midnight the party fireworks detonated at our level in front of our eyes. The flares illuminated some fog patches from the valley and produced greenish and brownish coronas. Some of the original flares could have been green but the effect could also be due to scattering from the firework smoke particles. We wish you all a wonderful New Year and hope that you see this and plenty more atmospheric optics phenomena in 2007.
