Results of the IMO Video Meteor Network - June 2007 =================================================== June wasn't very favourable to the video meteor observers. As in May, it was often rainy and overcasted. However, some observers were more lucky than others. For Joerg Strunk, Bob Lunsford and Stephen Evans, it was one of the worst months in their observation series. Bernd Brinkmann, on the other hand, managed to collect 26 observing nights, and Sirko Molau as well as Javor Kac passed the 20 observing nights mark as well. That is even more amazing given the fact, that Bernd and Joerg observe in a double-station setup at a distance of little more than 50 km. For the second time in a row, we missed one observing night, but the data of Remo1 in Ketzuer is still missing. Maybe at least this camera enjoyed a few cloud gaps on June 29/30? With respect to the hardware, there have been some changes in Slovenia. The camera SRAKA of Mihaela Triglav resumed operation in mid-June, and Javor Kac started to operate a new camera dubbed ORION1. In addition, his other camera METKA was replaced by a new Mintron video module with the ExView HAD chip, which significantly increased the meteor number compared to his old module with the SuperHAD chip. Once more it was fascinating, how strong the meteor rate may change within a couple of days. Whereas in mid-January you get the subjective impression, that the meteor rate halves within a few days, it seems to double similarly abrupt in mid June (just before or at the solstitium). 1.
