Active: July 15-August 10

Maximum: July 28 (λo = 125°)

ZHR = 5

Radiant: α = 341° δ = -30°

Radiant drift: see Table 6

v∞ = 35 km/s; r = 3.2

TFC: α = 255° to 000° δ = 00° to +15°

choose pairs separated by about 30° in α (β < 30° N)

 

Very little information has been collected on the Piscis Austrinids in recent decades, so the details on the shower are not well confirmed, and it seems possible the ZHR may be a little optimistic. However, that impression may be due simply to the large amount of northern hemisphere summer data, and the almost complete lack of southern hemisphere winter results, on it. The shower seems to be rich in faint meteors, rather like the nearby ANT and SDA, so telescopic work is advisable to try to establish more about it. First quarter Moon for the probable maximum will set between 22h-00h (its setting time is progressively later for places further south).
