was an event that is reported to have occurred on 13 October 1917, attended by a large crowd who had gathered in Fátima, Portugal, in response to a prophecy made by three shepherd children. The prophecy was that the Virgin Mary (referred to as Our Lady of Fátima), would appear and perform miracles on that date. Newspapers published testimony from people who said that they had witnessed extraordinary solar activity, such as the Sun appearing to "dance" or zig-zag in the sky, careen towards the Earth, or emit multicolored light and radiant colors. According to these reports, the event lasted approximately ten minutes.   first time i've read about this event, but this definitely sounds like it deserves looking into more.
