Give Mom a Diamond

   About an hour after local sunset, on Mother’s Day May 12th, go outside and face south and look for the 8-day old waxing gibbous Moon to be near the star Regulus. Then look for the bluish-white colored star Spica.
   Spica, a star in Virgo the Harvest Maiden, marks the lower corner of an *asterism known as ‘the Diamond of Virgo’. To see the asterism look up to the left from Spica for the reddish star Arcturus in the kite-shaped constellation Bootes the Herdsman. Then look nearly straight up, the zenith, for the dimmest of the diamond stars, Cor Caroli in Canes Venatici, the Hunting Dogs. Then look down to the right for the star Denebola, the tail of Leo the Lion.
   Look toward the western horizon for a reddish star, actually the ‘Red Planet’ Mars.

*An asterism is a group of stars forming a recognizable pattern using stars within a constellation or by combining stars from more than one constellation. For example, the Big and Little Dipper are asterisms.
