In that day the comet Lulin has been positioned just southwest of the Praesepe in Cancer. I captured these images under Moonlight with an age of 9.4, only a short dust tail can be detected. The comet has already started to withdraw from the Earth, has a visual brightness of about 6th magnitude or so, a bit dimmer than that in last month.
