Comments: Comet Tuttle was flying by the Triangulum galaxy, M33, and they
were at their closest now, only 20' separation. The much larger and
elongated M33 possessed a significantly lower surface brightness than the
round fuzz-ball Tuttle, which was easier to see. I could glimpse comet
8P/Tuttle with my naked eyes! This was the first time it had become
visible without optical aid since its discovery in the year of 1790. I was
able to see comet Tuttle naked eye together with 17P/Tuttle _exactly_ at
the same time. Their separation was only 22° so when I stared at a point
between them and to the right of the connecting line, I could hold them
both with averted vision. This is unprecedented in history, two short-
period comets seen simultaneously without optical aid! This was the first
clear night without moonlight the past weeks. Site: Virsbo, Sweden
