Keeping an eye on 13P/Olbers shows little improvement over April 29's outburst (see
https://astrob.in/piixe0/B/). In fact, I've attempted once more to overstretch the image to pull out any extended tail structure, with little success. I was hoping with the recent multiple CME's and fairly major solar flares would encourage 13P to be a little less shy. Still a difficult evening object holding steady in horizon position all month.
