Ten. This is the number of nights comet C/2013 UQ4 Catalina was observed via the Virtual Telescope. For sure, it is clearly fainter than in mid-July, but its dusty tail is still well visible...

After a couple of nights of rainy weather, at Virtual Telescope we managed to image comet C/2013 UQ4 Catalina again. This time we were able to capture less signal, as clouds were back after only 20...

For the 8th night (almost) in a row, Virtual Telescope visited comet C/2013 UQ4 Catalina, under good sky conditions. The dusty pattern of the comet is showing very well, as usual, making this comet...

After a few days, the Virtual Telescope observed again comet C/2013 UQ4 Catalina, while it is leaving the inner Solar System and constantly fading. The image above comes from 19, 180-seconds exposures, median combined to remove...

After a one-night break because of the weather, the Virtual Telescope observed again comet C/2013 UQ4 Catalina. The image above comes from 19, 180-seconds exposures, median combined to remove the presence of the stars...

After five nights of observations  in a row, we managed again to put together all the images we have of comet C/2013 UQ4 Catalina, showing how this comet evolved from 9 to 13 of...

While the bright, full Moon was in principle a serious obstacle, at Virtual Telescope we managed to observe comet C/2013 UQ4 Catalina again on 12 July, early in the evening, before the Moon was...

Despite the VERY bright Moon, this morning at Virtual Telescope we imaged again comet C/2013 UQ4 Catalina. The image above comes from 19, 180-seconds exposures, median combined to remove the presence of the stars...

After three nights of coverage of comet C/2013 UQ4 Catalina, it is interesting to see how the aspect of the comet changed because of the evolving geometry, while the comet is leaving the inner...

For the third night in a row, at Virtual Telescope we visited comet C/2013 UQ4 Catalina again. After the first night, we covered its close approach, and now  while it is leaving us. This...

After the first, nice visit of this object the previous night, the Virtual Telescope looked again comet C/2013 UQ4 Catalina, soon after the Moon left the sky. The comet was just approaching its minimum...

On 23 Oct. 2013, the Catalina Sky Survey in Arizona discovered a new, apparently asteroid-like object, moving on a rather cometary orbit: it received its provisional designation 2013 UQ4. This happens from time to...
