| Комментарий | Funny how through the eyepiece it looked nothing like it is currently photographing! Despite the growing moonlight there was a large very faint outer coma that I could make out to about 8' in diameter, a small brighter inner coma and a bright central condensation that was visible in averted vision. The coma appeared elongated roughly to the east and also to the east was a short subtle brightening that was probably the dust tail. But the latter was so indistinct that it was impossible to assign a P.A. with any certainty. Moonlight interference. |
