Between 23:00 and 24:00 (UTC+8) on May 3, LIU Qian Yu(刘乾煜) captured a supreme light pillars event occurring within high-level clouds(or falling virga in middle-level) in Anqing City, Anhui Province, China. The clarity of the observed 'mirrored city streets' map' is very very distinct and remarkable. JIA Hao and I consider this record to be among the most outstanding documentations of such phenomena worldwide.

As an experienced astrophotographer and member of the Chinese ice halo community, LIU promptly switched to an circular fisheye lens, thereby capturing a full view of this sky wonder. A meteorological chart corresponding to approximately three hours offset from the time of photographic observation is attached, with our appreciation extended to QIAN Kun for supplying this chart.
Song Xi Pei contributed to the comparative works between LIU's image and maps.

It's almost unreal. The best case indeed, and by some margin at that. We have get those automatic sky-map cameras running in every city.
ReplyDeleteOn another note, I wonder if the apparent diffuse light at the zenith seen in the first natural version is just a co-incident brighter cloud. Or could it be a sort of zenith spot from the city glow? By application of Gaussian blur the streetlines can be removed.
