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...

Finally, at Virtual Telescope we observed the dwarf planet (1) Ceres and the asteroid (4) Vesta at their minimum angular distance (10 arcminutes, 1/3 of the angular size of the full Moon disk), sharing...

While Ceres and Vesta prepare their closest conjunction. at Virtual Telescope we imaged this unusual couple again. Above is an image showing the dwarf planet Ceres and the asteroid Vesta less than 12 arcminutes...
asteroid / conjunction / event / free
Next 5 July, we will show live the amazing, rare conjunction between the dwarf planet Ceres and the asteroid Vesta. While waiting for this big show, we captured this view already showing the couple...
We recently installed for testing an all-sky camera at the Virtual Telescope site, with the intention to monitor the sky both for clouds and meteors/fireballs. Fist tests were very promising and last night we...
