82 Alkmene

82 Alkmene ( ) is a main-belt asteroid. Alkmene was discovered by R. Luther on November 27, 1864, and named after Alcmene, the mother of Herakles in Greek mythology. Based on IRAS data, Alkmene is estimated to be about 61 km in diameter.〔 A satellite has been suggested based on 1985 lightcurve data.〔http://www.johnstonsarchive.net/astro/asteroidmoonsq.html〕
Asteroid Alkmene occulted the apparent magnitude 7.5 star HIP 99229 in the constellation of Capricornus on 18 September 2014 around 06:41 UT (17 September 23:41 PDT) and was centered on Sacramento, CA.〔(Interactive GoogleMap of Shadow Path )〕〔http://www.asteroidoccultation.com/2014_09/0918_82_32999.htm〕 Alkmene projected an eclipse shadow that moves at about 2 miles/second. Asteroid occultations allow for accurate 2-dimensional mapping of an asteroids silhouette when observed by multiple telescopes separated by about 10km.
