КомментарийAlthough I was already planning on making an effort this morning, seeing these after I woke up rather inspired me. I had made an attempt yesterday morning from close to my residence, but even from that site I had to wait for the comet to rise above a distant hill, and by the time it did so the sky was too bright (even though I could see an 8th-magnitude star in the field). This morning, I made an hour's drive to a site with a perfectly flat horizon in that direction, and clearly saw the comet, even though it was less than five degrees above the horizon, in twilight. The sky conditions were perhaps not excellent, but they were decent enough.
