(It became invisible. The sky was very clear and I could see many faint stars not printed in my chart
based on GSC. I recorded them, but they are 15-16 mag stars recorded in the USNO-A2.0 catalog.
The comet must have been among those stars, but I could not find it.)
2006  5  2.70   S 13.8 HS  40.0L 257  0.6  2            YOS  Gunma, Japan
(Very tiny object was visible at the position. Similar to a faint star, and near limit.
But I think I could see the component AS.)

(I cannot observe it for a long time enough because rain started falling down suddenly.)

(Very faint object near limit of telescope. Position and observed motion along magnitude 13.7 star [TA]
in agreement with orbital elements from MPEC-H48.)

(Definitely seen with 0.41-mL. Motion checked during a 2h period. TheSky6 shows no bright stars or
galaxies near comet'sposition.)
