EDMOND database 2016 from January to March Jakub Koukal Valašské Meziříčí Observatory, Vsetínská 78, 75701 Valašské Meziříčí, Czech Republic [email protected] The first quarter of 2016 suffered from poor weather conditions over Europe. A summary is given for the data reported so far by a number of participating networks. Results with the trajectory plots and the radiant distributions for both wide angle cameras and narrow field cameras are presented.

1 Introduction

2 Results (wide-angle cameras)

The weather in the first quarter of the year 2016 in Europe was not favorable. Nowadays (May 26, 2016) data from the following networks are in the EDMOND database (Kornoš et al., 2014a):

During the first quarter of 2016 all 99 working stations (of the networks listed above) together registered 25536 individual meteors. It was possible to calculate trajectories in the atmosphere and the meteoroid’s orbits in the Solar system for 4479 paired meteors. A ground map (projection of the meteor atmospheric trajectory on the ground) for these paired meteors is shown on Figure 1 and a map of the radiants of these paired meteors is shown on Figure 2. Most meteors were sporadic meteors (3208 orbits), others belonging to known showers – QUA (Quadrantids, 214 orbits), COM (Dec. Comae Berenicids, 71 orbits), ECV (η-Corvids, 27), TBO (12 Bootids, 27), LBO (λ-Bootids, 26), FPL (February π-Leonids, 24), JLL (January λLeonids, 23), XUM (χ-Ursae Majorids, 21), NBO (νBootids, 20), PVI (January π-Virginids, 20) and other meteor showers with one or more orbits from IAU MDC working list (Jopek et al., 2014).

The presented results are thus partial and they do not include results of all national networks from the first third of the year 2016.

During the first quarter of 2016 all 6 working stations together registered 766 individual meteors. For 152 paired meteors it was possible to calculate very accurate trajectories in the atmosphere and the meteoroid’s orbits in the Solar system. A ground map (projection of the meteor atmospheric trajectory on the ground) for these paired meteors is shown on Figure 3 and a map of the radiants of these paired meteors is shown on Figure 4. Most were sporadic meteors (126 orbits), with others belonging to known showers – QUA (Quadrantids, 3 orbits), PVI (January π-Virginids, 2 orbits), NBO (ν-Bootids, 2), FHE (f Herculids, 2) and other meteor showers with one orbit from IAU MDC working list (Jopek et al., 2014).
