Results of the IMO Video Meteor Network - May 2006
==================================================

May stared promising. Spring weather prevailed in the first part of the month,
giving central European observers the chance for long observing series. In
California, Bob was not so fortunate, but on the other hand he managed to
record 69 meteors within 72 minutes during the eta-Aquarid maximum. Such
activity is usually only observed during the Perseids or the maximum of
sporadic and ecliptical activity in fall.

In the second half of the month, winter sent a last goodbye. Once more there
was snowfall below 1000m altitude in southern Germany, and daytime temperatures
reminded us to the cold season. Even so fewer observations could be collected
in these cloudy days, there was still at least one camera active each night.

After the spectacular breakup of comet 73P/Schwassmann-Wachmann, astronomers
became intrigued in the last days of May and early June. Orbital calculations
had shown, that the corresponding particle cloud would pass Earth at too a
big distance, so that we could not expect unusual meteor activity. Still
everybody was curious, whether the comet dust would reach Earth, anyway,
resulting in a Tau-Herculid outburst. As mentioned before, the outcome of
the video network was limited in these days due to the unfavourable weather.
Most data could be collected on May 31 and the following night, where 7 out of
124 meteors were classified as Sagittarids and 9 as Tau-Herculids. In the four
preceeding nights, an overall of 79 meteors could be secured, 5 of which being
classified as Sagittarids and 4 as Tau-Herculids. Hence, we can conclude from
the existing material, that at those times were our cameras were active, comet
73P/Schwassmann-Wachmann presented only marginal meteor activity to the
observers.
