Active: December 1—15; Maximum: December ∼ 6 (λ⊙ ∼ 255°); ZHR ∼ 10;
Radiant: α = 123°, δ = −45°; Radiant drift: see Table 6;
V∞ = 40 km/s; r = 2.9;
TFC: α = 90° to 150°, δ = −20° to −60°; choose pairs of fields separated by about 30° in α,
moving eastwards as the shower progresses (β < 10° N).
This is a complex system of poorly-studied showers, visible chiefly to those south of the equator. Up to ten sub-streams have been proposed, with radiants so tightly clustered, visual observing cannot readily separate them. Imaging or telescopic work would thus be sensible, or very careful visual plotting. The activity is poorly-established, though the higher rates seem to occur in early to mid December, with a waning to new Moon this year. Some PUP activity may be visible from late October to late January, however. Most PUP meteors are quite faint, but occasional bright fireballs, notably around the suggested maximum, have been reported previously. The radiant area is on-view all night, but is highest towards dawn.
