               of 81.  He spent his evenings as a successful discoverer
               of comets and asteroids, measuring their positions and
               calculating their orbits.

Mar  4, 1774:  William Herschel's first recorded observation of the
               Orion Nebula.

Mar  4, 1866:  Norman Lockyer began his spectroscopic observations of
               the sun.  Codiscovered helium in the sun.

Mar  8, 1618:  Johann Kepler discovers Third Law of Planetary Motion.

Mar  8, 1804:  Alvan Clark, noted for his fine large telescope objectives,
               is born.  He founded the firm that built the Lick 36 inch
               and Yerkes 40 inch refractors.

Mar 11, 1811:  Urbain Leverrier, French mathematical astronomer and
               director of Paris Observatory, is born.  Predicted the
               existence of Neptune (with J. C. Adams) before its optical
               discovery (in 1846).

Mar 13, 1781:  William Herschel discovers Uranus with a 6 inch homemade
               reflector.

               died at the age of 71.

Mar 14, 1897:  Albert Einstein born.

Mar 14, 1936:  "The whole procedure of [shooting rockets into space] ...
               presents difficulties of so fundamental a nature, that we
               are forced to dismiss the notion as essentially impractic-
               able, in spite of the author's insistent appeal to put
               aside prejudice and to recollect the supposed impossibility
               of heavier-than-air flight before it was actually accomp-
               lished."
               ---Richard van der Riet Wooley (British Astronomer) re-
                  viewing P.E. Cleator's "Rockets in Space"

Mar 15, 1964:  Periodic comet Schwassmann-Wachmann suddenly brightened
               by six magnitudes, from 18 to 12.

Mar 17, 1725:  Mercury, Venus, Mars, and Jupiter were so near to each
               other in the sky as to be visible in the same telescopic
               field of view.

Mar 17, 1846:  F. W. Bessel, who determined the distance to the star
               61 Cygni, died.  Director of Koenigsberg Observatory in
               Germany, he revolutionized the art of precise astronomical
               measurements.

Mar 18, 1934:  A great fireball, widely seen in Western Canada, exploded
               over Alberta.

Mar 22, 1799:  F. W. A. Argelander, German astronomer who catalgoued and
               charted 324,000 stars and founded the science of variable
               star study, was born.

Mar 25, 1655:  Dutch astronomer Christiaan Huygens discovered Saturn's
               moon Titan, with a non-achromatic refractor 12 feet long.

Mar 26, 1859:  Lescarbault's supposed discovery of an intra-Mercurial
               planet, Vulcan.

Mar 28, 1802:  Amateur astronomer Olbers discovers the asteroid Pallas.
               It was his first.

Mar 29, 1807:  Amateur astronomer Olbers discovers the brightest asteroid,
