If you subtract 911 days from 8/11 you land on 2/11/17. On that day there was an eclipse.
Subtle lunar eclipse on February 10-11
The Americas and Greenland see the penumbral lunar eclipse Friday evening. Europe, Africa, and Asia see it Saturday morning.
The star near the moon on eclipse night is Regulus, sometimes called the Heart of the Lion, brightest star in the constellation Leo.
There's your lion...
Although the residents of Australia and New Zealand will miss out on this penumbral lunar eclipse completely, a different sort of eclipse will occur in their sky. The moon will occult (cover over) Regulus, the brightest star in the constellation Leo, on the night of February 11. For instance, from Perth, Western Australia, the occultation takes place on February 11 from 8:39 p.m. to 9:51 p.m. local time.
Where is Regulus on 8/11?
Although best seen in the evening in the Northern Hemisphere in late winter and into summer, Regulus can be found at some time of night throughout the year except for about a month on either side of August 22, when the sun is located in Regulus’ direction in space
Regulus is the only 1st-magnitude star to sit almost squarely on the ecliptic, which marks the path of the sun, moon and planets across our sky. That means it can be seen from the entire Earth.
Bright planets sometimes pass near Regulus, and every month the moon passes no more than about five degrees away. In some years, the moon occults (passes in front of) this star as seen from our earthly vantage point. In fact, Regulus just underwent a series of occultations – one during each month that this star was visible – starting on December 18, 2016, and concluding on April 24, 2018.
