(meteorobs) Result OSVDA 17/18 and 18/19 november
<pre>
These are my results, obtained during the DMS expedition to Spain. In two nights I managed to do about 4 hours and 20 minutes of observing under acceptable conditions, the peak is not included unfortunately.
During the peak we were able to see a lot of meteors but the sky conditions were changing too much (and very inconsistent across the sky) to get reliable results. I noticed a sharp increase at about 3:45 UT, a peak between 4:00 and 4:20 of about 40 meteors per 5 minutes, then a drop to 3 meteors per 5 minutes around 5 UT, another climb starting at 05:15 and a peak around 5:35 of about 15 meteors per 5 minutes.
