Dunque è sopravvissuta, non sarà più la cometa del secolo ma la si dovrebbe comunque poter osservare al binocolo, e forse anche a occhio nudo, nei prossimi giorni. La Comet Section della BAA ha diramato questa news:
It seems that the comet has survived its close encounter with the Sun, thus increasing the chances of there being something to see in the coming weeks. You will need to get up early as the comet is most likely to be seen between 06:30 and 07:00 low in the east-south-east over the next few days, most likely from December 3 onwards. Tomorrow morning is probably too soon, but you never know, particularly if the comet is brighter than expected. For the next week you will need a clear horizon as well as clear skies as the comet is very low down. It gets higher in the sky, but will fade, though the tail may become more prominent. The best views might come around 06:00 between December 7 and 14, and at the end of this period you might also see a few Geminid shooting stars. By mid December it will be visible in the evening, and by Christmas it will be visible all night, though you may need binoculars to see it. Sky & Telescope have some finder charts at http://www.skyandtelescope.com/observing/ataglance
There is another comet visible from the UK, 2013 R1 (Lovejoy), which may be seen in binoculars as a fuzzy patch, about half the size of the Moon, roughly 15 degrees west of the Plough near the top of Bootes. It is at nearly the same altitude as the Plough at 18:00. It continues to move west at two to three degrees per day.
