This phenomenon in Fatima, Portugal on October 13, 1917 may have been due to a combination of astrological factors. These were:
1. The Sun was in conjunction with an exalted Mercury in Virgo. 2. Rahu, signifying mass hysteria, was placed in the lagna at that time, about 1:30 pm 3. There was a conjunction of the malefics Mars and Saturn in the 8th house of mystery and fear. At that time, there were about 70, 000 people who witnessed the phenomenon. https://youtu.be/L5IlaV6ZI_c?t=146 https://youtu.be/L5IlaV6ZI_c?t=146
