Four months after our last published observation, we slewed our robotic instruments to comet C/2013 US10 Catalina again, despite a very bright Moon and a poor altitude of the comet. The image above comes from the average...
Nine days after our previous, first visit, we spied comet C/2013 US10 Catalina again, under significantly better geometry, that is with the comet a few more degrees above the horizon (though still far from the ideal)....
After all, this 2015 we will have another Christmas comet! After last year’s comet C/2014 Q2 Lovejoy, those living in the northern hemisphere are saluting comet C/2013 US10 Catalina, already giving a stunning show...
After waiting for quite a lot of time, comet C/2013 US10 Catalina is finally showing in the northern skies. This comet has a good potential to be a nice comet in the next weeks, perfect...
As you know, at Virtual Telescope we managed to cover quite extensively the passage of comet C/2013 UQ4 Catalina while at its minimum distance from the Earth, last July. Then, the comet constantly reduced...
After ten days from our last observations, at Virtual Telescope we imaged comet C/2013 UQ4 Catalina again, despite it was only around 30 degrees above the western horizon, ad dusk. The image above comes from...
After almost ten days of cloudy/unfavorable weather, we imaged comet C/2013 UQ4 Catalina again, finding it much fainter than the 24 of July. The image above comes from 13, 180-seconds exposures, median combined to...
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...
