Wave of Darkness - Oshkosh, Wisconsin, 1886

No one can explain the wave of darkness that swept over Oshkosh, Wisconsin at 3:00 in the afternoon on March 19^th, 1886.  Within the span of five minutes, it was as if night had settled over the town.  Horses were spooked and people scrambled through the streets. But the inexplicable wave of darkness lasted only 10 minutes before abating.

The local newspaper reported that towns to the west of Oshkosh, WI had experienced the same phenomenon just before residents there, indicating the wave of darkness had traveled from west to east.  There were no air currents overhead, the newspaper said, nor was there a solar eclipse on March 19^th, 1886.
