light pillars over Pennsylvania
On November 19, 2008, thousands of residents in and around Philadelphia, Pennsylvania, watched in awe as dozens of stationary light pillars loomed up in the evening sky.

The above photo is one of a series of seven, taken by David WEI from Plymouth Meeting, Pennsylvania, at around 9 p.m. EST facing southeast. David used a Canon 40D camera fitted with a 17 mm wide-angle lens. The exposure time was presumably 1.3 seconds and the aperture was set at f/2.8.

See our case example Philadelphia November 19, 2008 for an analysis of this photo.
