Most of the detections were already published in several issues of SELENOLOGY TODAY.

We begun our survey in 2009 and spent the first two searching years without detections. We captured the first impact candidate when we modified our procedure of scanning and the aperture of one instrument. At the beginning of 2011 we changed from a 20cm to a 28cm Schmidt-Cassegrain telescope.

Our observatories are located 13km apart. Not very far, but enough to discriminate for possible glints of very high satellites.

When the phase of the Moon is good, we observe every possible evening/morning. We observed so far for xx hours at the evening (past new moon) and for xxx hour at the morning (pre new moon). The rate of detected impact candidates at waxing is 1 every 10h; at waning 1 every 28h. Continue reading
