M11 Daily Motion
M11 will rise at 13:40, reaching 45° when twilight begins at 18:37. It will reach transit at 46° by 19:20 and will set before twilight ends at 01:00.M11 will be visible until November, 22, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.
