Marco Langbroek: Table


Hello all,

I finally have my data of the November 17-18 Leonid storm ready. Below, I will give a table with raw data, and:

a PRELIMINARY ZHR curve from my data for the period 1:05-4:14 UT. Reduction procedure can be found in Peter Jenniskens paper in A&A 295 (1995), 206; and in my paper in Meteoritics & Planetary Science 34 (1999), 137. I used gamma=1.4 in radiant altitude correction, r=3.5 (as resulting from my mag. estimates: 3.5 +- 0.8. No magnitude data from period 1:49-2:49!!) in limiting magnitude correction, and my Cp is 1.4. ZHR's are only given for radiant elevations above 20 degrees.

A fit to the ascending and descending branches gives a maximum at 2:03 UT with a maximum activity equivalent to a ZHR of about 3200. Indeed, this is where I have my highest count (39 Leonids in one minute at 2:03 UT, Lm +6.6; this one minute count taken face value provides a ZHR of 3587 +- 575). With an uncertainty of only a few minutes, David and Rob's peak prediction thus was correct. They only need to adjust your activity level prediction model slightly!

The slopes of the peak are well defined, symmetric and suggest B=20 (see above papers). After 3:00 UT with ZHR's below 200, there is some indication of a background taking over.

note: when plotted in a diagram with the ZHR axis logarithmic,
the activity profile has a nice well defined shape! See also
