α–Capricornids (CAP)

Active: July 3 – August 15; Maximum: July 30 (λ⊙ = 127°); ZHR = 5;

Radiant: α = 307°, δ = −10°; Radiant drift: see Table 6;

V∞ = 23 km/s; r = 2.5;

TFC: α = 255° to 0°, δ = 0° to +15°, choose pairs separated by about 30° in α (β < 40° N);

IFC: α = 300°, δ = +10° (β > 45° N), α = 320°, δ = −5° (β 0° to 45° N), α = 300°, δ = −25°

(β < 0°).

The CAP and SDA were both definitely detected visually in former years, standing out against the much weaker other radiants supposed active in Capricornus-Aquarius then. Whether the CAP can still be detected as visually separate from the new ANT radiant area is unclear, as its radiant now partly overlaps that of the large ANT region. Observers failed to find a clear maximum for the shower in 2009, which does not augur well, though it had been hoped their bright, at times fireball-class brilliance, combined with their low apparent velocities, might make them distinctive enough to still be detected by means other than video. A minor enhancement of CAP ZHRs to ∼ 10 was noted in 1995 by European IMO observers. Recent results suggest the maximum may continue into July 31.

Να προσθέσω ότι το μέγιστο θα είναι μαζί με τους δ–Aquariids (SDA) στις 30 Ιουλίου, την ημέρα που θα είμαστε στην 5ΠΣΕΑ
