The Moon is close to Full these days which is not helping with meteor detection. Still the nightly numbers of detections is similar to those of the past week so maybe the Moon isn’t being as big of a bother as expected.
Over the past three nights, the Earth was passing close to the orbit of now defunct comet C/2012 S1 (ISON). Only a single possible ‘ISONid‘ was detected and the important word is ‘possible‘. The comet passed through this part of its orbit around 74 days ago so it is unlikely that much dust should still be in this part of its orbit. In future years, it is very possible that the dust will become more spread out (due to differences in their orbital period which do to various effects will be substantially smaller than that of the main comet) and a annual, though weak, ISONid shower will be visible.
