Southern Delta Aquariids

Cuno Hoffmeister and a team of German observers were the first to record the characteristics of a Northern Aquariid radiant within the stream around 1938.

[3] That was accomplished by astronomer Mary Almond, in 1952, who determined both the accurate velocity and orbit of the δ Aquariids.

She used a "more selective beamed aerial" (echo radio) to identify probable member meteors and plotted an accurate orbital plane.

Her paper reported it as a broad "system of orbits" that are probably "connected and produced by one extended stream.

Since the radiant is above the southern horizon for Northern Hemisphere viewers, meteors will primarily fan out in all compass points, east, north and west.
