Results of the IMO Video Meteor Network - February 2008 ======================================================= A few days ago we received the sad news that long-term video observer Stephen Evans died from a massive heart attack. Even though he rarely enjoyed perfect weather at his observing site in England, Steve was a reliable constant in the IMO network. He regularly provided observations to our network that were obtained with great care and characterised by their precision. Steve always shared a few encouraging words with others and there was hardly anything I had to correct in his data. What a pity that he left us on such short notice. On the other hand, four new cameras stared operation in February. I myself installed REMO2 in Ketzuer, which is operated fully autonomous as her twin camera. Now REMO1 is covering the eastern sky up to zenith, whereas REMO2 observes westward of the zenith. With BMH2, Flavio Castelani installed a second camera at his site as well. For the first time we could welcome a Portuguese observer. Rui Goncalves is operating a camera system similar to REMO2, i.e. a Mintron camera with a 3.8mm f/0.8 Computar lens. Also beyond the big ocean the camera network has grown, as Carl Hergenrother is operating a Supercircuits PC164C camera with a 4mm f/1.2 Computar lens from Tucson / Arizona. Lets come to the observation result in February. These were once more extraordinary, especially if we keep in mind that data of SRAKA are still missing, and of REMO1 and REMO2 are only available for the first part of the month so far. Thanks to the exceptional weather in central and southern Europe, those 27 cameras operated last month were able to collect more than 2200 hours of effective observing time - more than in any other month before. You really have to melt in your mouth that the "dirty" month February with only 29 nights outperformed all others! With respect to the meteor number, it could not compete with August or October, but those almost 6000 meteors enlarged the data set for February by well over 50% in just one year. Hence, we should now be able to detect also weak showers at the begin of year reliably in our database. 1.
