(meteorobs) Leonid radiant position
Leonid radiant position
After receiving another set of video data from Mirko Nitschke, who operated
an image-intensified video camera on Teneriffe, I have computed the mean
radiant position of the Leonids during the 1999 meteor storm.
Using the RADIANT software of Rainer Arlt an extremely compact radiant plot
was obtained, which is shown at www.imodot net/leo99. An overall of 633
single-station Leonid recordings were used.
The resulting position (solar longitude = 235.29 deg) is
alpha = 153.6 deg (+/- 0.1 deg) and delta = +21.9 deg (+/- 0.1 deg).
Looking at the two subsets of Leonids recorded before and after 2:00 UT, which
might mainly be caused by meteoroids from different returns of the parent
comet, no significant radiant shift can be observed in the data available
so far.
