(meteorobs) more details on the October Camelopardalids

[Sirko Molau]

Folks,

currently I have the datasets from four cameras available: The image-intensified
cameras OND1 (operated by Rosta Stork) and AVIS2, and the Mintron cameras
Mincam1 (both operated by Sirko Molau) and METKA (operated by Javor Kac).

Just as last year, the image-intensified cameras recorded only few October
Camelopardalids compared to the overall number of meteors. Those 6 OCAs of AVIS2
appeared between 23:57 and 02:26, and the 8 OCAs of OND1 between 01:27 and
03:31.
In the data of the two non-intensified cameras, however, the shower was much
more prominent.

Camera    Time [UT]   SPO  OCA Other
------------------------------------
OND1     00:18-04:10   71   8   41
AVIS2    21:03-04:16   60   6   22
Mincam1  17:27-04:35   23  11   15
METKA    17:43-04:20    7   5    1
------------------------------------

The hourly distribution of the OCA recorded by Mincam1 and METKA shows a clear
peak between 1 and 2 UT:

Time [UT]   SPO OCA Other
-------------------------
18:00-19:00  2   0   0
19:00-20:00  0   0   0
20:00-21:00  2   0   0
21:00-22:00  3   1   2
22:00-23:00  1   1   2
23:00-00:00  5   0   2
00:00-01:00  3   2   4
01:00-02:00  1   7   2
02:00-03:00  6   3   3
03:00-04:00  5   2   0
04:00-05:00  2   0   1
-------------------------

This confirms that the October Camelopardalids are an annual meteor shower with
a width (FHWM) of just about two hours.

A more detailled analysis will follows when all data from the camera network are
available.

Best,
Sirko
