The comet's tail seems to be growing longer each night. I could easily see it extending 5 degrees with the naked eye and the nucleus and coma must be 2nd magnitude although this was just a guesstimate. There were also some wispy clouds scattered across the sky but they didn't interfere with comet viewing until it was well into twilight.
