Michael,
You ask below about occultations of delta Scorpii.
Several years ago, Jean Meeus sent a special book he
prepared for me giving the Besselian elements of
all stars brighter than mag. 3.1 occulted by the
Moon from 1900 - 2099. The next occultations of
delta Scorpii occur on the following dates:
2003 Sep. 2, Sep. 30, Oct. 27, Nov. 24, & Dec. 21
2004 Jan. 17, Feb. 14, Mar. 12, Apr. 8, May 6,
June 2, June 29, July 27, Aug. 23, Sep. 19,
Oct. 17, Nov. 13, and Dec. 10
2005 Feb. 3.
Then there are no more occultations of the star
until another similar series starting on
2010 Sep. 13.
