9:10 to 9:30 PM local time. Using my 28x110s, I had a closer look at 46P / Wirtanen. Through these large and higher powered binoculars, the comet's fuzzy circular form dominated the center of the FOV. It was now evident that the comet's circular halo of light was not nearly as uniform as it had appeared last night through my much smaller 16x70s. In fact, it rather appeared to be subtly (but quite noticeably with the aid of averted vision) lumpy, with thicker patches and knots of light distributed seemingly at random, but with most of their concentrations in the N, W, and S of the halo, leaving the E largely smooth. However, not one of the thickenings or knots was especially noteworthy for its prominence. I could verify that the comet has no definite nucleus, but merely a gradual brightening towards the center from the outside in. It also has no sharply defined edge to its glow, or even a certain edge at all, for averted vision will only extend the initially perceived boundary further out into the void. As a side note, the comet has moved a bit further north of where it was last night, and I now clearly saw it by naked eye; faint, but certainly there, to the left (E) and N of Azha.
The temperature was a very chilly -20*C. Ice coated the barrels of my binoculars and the cold greatly stiffened the grease in the mount head. The sky conditions were much like last night's were, only minus any hint of wind, and there was surprisingly excellent seeing as well as excellent transparency in those areas of the sky that were clear. The scattered patchy clouds, borne upon the wings of some upper-atmospheric wind, rolled in unstoppably from the N in ever-increasing thickness and tightness of formation, appearing deceptively stationary as they took over the sky. The session, which began under skies that were mainly clear, ended under skies that were nearly fully cloudy.
The planet Mars, dominating at medium altitude the WSW, appeared as a relatively bright deep orange star. Deneb in the NW, the Hyades, the Pleiades, Orion, and Cetus all appeared and disappeared at different times in between breaks in the cloud. One very bright meteor slashed nearly horizontally across the high SE sky, swift and yellowish of hue, traveling perfectly the length of a long thin break in the cloud cover.
Edit: I just finished disassembling my equipment. It is now completely cloudy, not one star in sight. And all that bare metal...ouch, ouch, ouch!
