SIGISMONDI (AAVSO Observer and author of a recent JAAVSO article on Mira) both reminding us that August 13, 1596 is the date that David Fabricius discovered Mira and pointing out that Mira is currently at maximum - perhaps in celebration of it's anniversary! The predicted date of maximum from AAVSO Bulletin 65 is August 5, 2002. Mira is known to stay at maximum for about a week. Recent observations range from magnitude 2.9 to 3.6 and are given below: AAVSO Observer AAVSO Observer UT Mag. Initials UT Mag.
