The CAP and SDA radiants were both denitely detected visually in former years, standing

out against those much weaker ones supposed active in Capricornus-Aquarius then. Whether

the CAP can still be detected as visually separate from the 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 for example. However, their bright, at times fireball-class

brilliance, combined with their low apparent velocities, might make them distinctive enough to

be detected still 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, with similar lunar conditions to the 30th.
