Upper Lowitz arc

Glenn Wolford photographed this display on November 9 in Syracuse, N.Y., U.S.A. The noteworthy feature is the upper Lowitz arc from Parry-Lowitz orientation. Click on the photo for simulation. Lowitz crystal tilts in the simulation are 13 degrees and sun elevation 30 degrees. Simulations and crystal figures from Jukka Ruoskanen's software. See also another photo ( 1 ).
