Whilst sending my visual results I saw the mail with Ondrejov radar
results, and I still had time for a short additional watch using
14x100B's. I had to spend time dark adapting again, and dawn was
approaching, so I could not achieve a longer watch period, still my
negative result shows that any substantial Linearid activity at this
moment must be of very faint telescopic meteors (below visual mag +9).
14x100 binoculars; field 3.5 degrees
Limiting magnitude about 12.1-12.5
Field: R.A.=13h 20m Dec.=+86d 30' (J2000.0)
Interval: 0518-0603 UT. Effective time: 30 minutes
Observed meteors: 1 probable TAU (mag 7) and 1 SPO (mag 9.5)
Observer PERAF = Alfredo Pereira
Cabo da Roca, Portugal (Lat. 38d 46' 52.1" N Lon. 9d 28' 33.4" W Alt. 235m)
Cheers,
