- Hi all,
I am now at the limit estimating 17P with reliability from my usual observing
place. On Jan. 29, I was at my parents home, in the Erzgebirge mountains, 6.5 mag
at the zenith and 17P was easy to spot with the 3.5x15 opera glasses and also easy
with the naked eye, although no longer possible to estimate without the opera
glasses due to its extent. I estimated 4.0 (at first uncertain, later corrected).
Last night, at my usual place at home (5.5 mag at the zenith) I saw it only with
the opera glasses as a ghostly patch, and only since I knew where to look. The
brightness estimate was of course only uncertain and I guess my observations for
17P from this place are soon over.
46P at 8.7 mag was way better to see than 17P! I never would have imagined to lose
a comet at 4 mag.
If they give you ruled paper, write the other way. * Juan Ramon Jimenez
