SOUTH DELTA AQUARIDS (maximum July 29 [broad])

(radiant drift map from IMO)



Moon: Full Moon (major interference)



Best viewing window: The last hour before morning twilight on Friday morning, July 27.



Recommended for: Early risers who want to brush up on their meteor observing before the Perseid peak.



The South Delta Aquarids are barely a major shower from 40 degrees N. They are part of a complex of radiants in Aquarius, Capricornus and Piscis Austrinus, all of which combine with sporadic and early Perseid activity to provide a nice display of meteors on moonless mornings in late July. The stream normally produces about 5-10 meteors/hour, with overall activity of about 30/hour under good conditions. This year the Full Moon severely restricts observing near the maximum, but a decent number of meteors should be visible a couple of days beforehand.



The South Delta Aquarids are medium-speed meteors, and tend to be faint on average. Meteors from this stream are easily confused with those of several minor showers with nearby radiants. The Piscis Austrinids have a radiant near the bright star Fomalhaut. A weak, diffuse radiant called the "anthelion" or "eclipticids" is also nearby. Farther west is the Alpha Capricornid radiant, which produces slower, often impressive meteors. You may not be able to assign every shower meteor to its correct radiant, but that doesn't mean you can't enjoy the show!



The faintness of most of this activity and the large number of faint sporadics mean that a dark sky is almost essential to the appreciation of this late-July enhancement of meteor rates. The radiants are higher in their sky for southern observers, but the Moon is still a pain. The best viewing window above reflects a short period between moonset and morning twilight.


The major showers (with ZHRs > 10) occur on approximately the same date each year. The actual predicted peak date and time may vary by a day or so due to leap year, so check the astronomy magazines or IMO Calendar for details.

Name ZHR Peak Date

Quadrantids 120 January 2-3
Lyrids 15 April 21-22
(ZHR variable up to 90)

Eta Aquarids 60 May 5-6
South Delta Aquarids 20 July 27-28
Perseids 110 August 11-12
Orionids 20 October 20-21
Leonids 20 November 16-17
storm at 33 year intervals

Geminids 120 December 13-14

Ursids 10 December 22

I can't give you specific times, but as a rule, best viewing is after midnight or 1 AM until the twilight of dawn.
