Dear all,
I updated the ZHRs, now determined with calculated radiant elevations.
Maximum values were close to 180 around Aug 12, 01h30m.
Intervall T_eff F lm Per kCg Aqu Cap Spo ZHR HR remarks
20h44-21h13 0.48 4(!) 5.5 2 0 0 0 0 = = bad data, clouds!
23h09-23h41 0.53 1.14 5.5 11 0 0 0 3 71 15
00h21-00h57 0.60 1 5.5 31 0 0 0 4 142 20
00h58-01h42 0.68 1 5.5 45 1 2 0 3 177 13
01h43-02h14 0.52 1 5.5 28 1 0 0 2 141 12
Note 1: n/a
Note 2: The r-value of the Perseids was assumed to be 2.6
Note 3: Compared to other observers, I am known to give a lower limiting
magnitude. Thus, the ZHR values might well be on the high side.
Intervall = start and end time of interval in UT
T_eff = effective observing time in hours
F = cloud cover correction factor
lm = limiting mag, determined by counting stars in IMO's reference
triangles
Per = no. of observed Perseids
kCg = no. of observed Kappa Cygnids
Aqu = no. of observed Aquarids (N/S etc. not distinguished)
Cap = no. of observed Capricornids
Spo = no. of observed sporadics
ZHR = ZHR of the Perseids
HR = hourly rate of sporadics (no zenith correction, r = 3)
Bye,
Detlef Koschny
