Southern Delta Aquariid Meteor Shower



Discovery of the Southern Delta Aquariid Meteor Shower

In 1870, G.L. Tupman recorded 65 meteors between July 27 and August 8. The radiant was incorrectly identified.


In 1926 and 1933, Ronald A. McIntosh made more observations, but it wasn't until 1939, when German astronomer Cuno Hoffmeister correctly identified the constellation Aquarius as the radiant for the Northern Aquariids. Turns out, there were two branches of this meteor storm, which were observed but not identified as two related showers, in 1949 by D.W.R. McKinley. Mary Almond, in 1952, finally identified the second radiant for the Southern Delta Aquariid Meteor Shower.


Their radiant lies near Delta Aquarii, one of the brightest stars in the constellation Aquarius. It produces 15-20 visible meteors an hour.
