Dear Colleagues, Since our last regular binary detection, which was 4029 Bridges in the April-May lunation, there passed three recent lunations without a regular binary discovery within our Survey. I have made a brief look at the negative fluctuation in our detection rate. During the twelve lunations since August 2005 till now, we have got 13 regular binary discoveries (plus a few non-regular ones, where additive two-period lightcurves but no mutual events have been detected in the survey phase on them). My running count shows that we have covered just 100 objects during the 12 lunations (though an actual number will be slightly higher, since a few Hungaria targets that Brian observes a bit separately have not been added to the data sample here yet; we do include them in blocks once in a while). A total number of surveyed objects during the 12 lunations is therefore about 110 or so. In the last three lunations, we have surveyed about 20 objects (again, a bit uncertain until we go through Brian's recent Hungarias observations to see which of them have been done sufficiently for the Survey). From the statistics, I am getting an estimate of a probability of the negative fluctuation in our binary discovery rate in the past three lunations of about 8%. Ok, it looks that we have got a little bit of bad luck recently. Let's hope it will come to an end soon, and we will get a new regular binary discovery before long. An updated list of targets is attached.
