Rare Occultation of Regulus!
News story originally written on May 13, 1999

An occultation of the star Regulus can be seen on May 21-22, 1999. A repeat of such a spectacular event will not occur again until the next century. Most of the United States, Mexico and Canada will have a great view. However, the extreme western part of the continent may be inhibited by daylight.

An occultation is a type of eclipse. In this case, the first-quarter moon will completely cover the star, hiding it from view.

Regulus, the brightest star in the constellation Leo, will be visible on the left side of the moon. Exact times according to location are listed on the link below, along with other information on the moon and occultation.

The public is encouraged to record the event. The International Occultation Timing Association (IOTA) will be interested in your videotape for future studies. Scientists plan to use the event to study climate.
