Astronomical Events for September 2014

The markup used here distinguishes between events of particular interest to novices, intermediate observers, and advanced observers. In the context of an event individual notes are also associated, in some cases, with an experience level. For example, an event that might be of interest to all may have some notes that would only be relevant to an advanced observer. These classifications have been made informally by me. This feature is experimental and subject to change or removal based on my experience with it.
