Comet C/2011 J2 Linear splitting: a new image (15 Oct. 2014)
Continuing our long coverage of this object, comet C/2011 J2 Linear and its fragment b was observed again under far-from-ideal weather conditions. While clouds were approaching and the sky was already significantly opaque, results...
Comet C/2011 J2 Linear splitting: a new image (10 Oct. 2014) and 34-days animation
As we saw last 6 Oct., comet C/2011 J2 Linear and its fragment b showed significant changes, with the smaller component apparently fading. The Moon was a serious issue, so further observations were planned...
Comet C/2011 J2 Linear splitting: a new image (6 Oct. 2014) and new animation
Continuing the constant monitoring of comet C/2011 J2 Linear and its fragment, new observations were performed on 6 Oct. 2014, while an almost full, extremely bright Moon was present, with a very serious interference....
The Comet and the Planet: comet C/2013 A1 Siding Spring meets planet Mars – 19 Oct. 2014, online event
*** See it LIVE: click here! *** *** See it LIVE: click here! *** Next 19 Oct. 2014, we will see an extremely rare event: comet C/2013 A1 will pass extremely close to planet Mars, about...
Comet C/2011 J2 Linear splitting: a new image (29 Sept. 2014) and further evolution
After we were informed about the discovery of a nucleus splitting event for comet C/2011 J2 Linear, providing prompt follow-up at that time, at Virtual Telescope the comet was constantly monitored and measured, in order...
Comet C/2011 J2 Linear splitting: a new image (24 Sept. 2014) and animation
As previously reported, at Virtual Telescope we provided a precious follow-up to confirm the nucleus splitting of comet C/2011 J2 Linear. Eleven days after our last observations, we managed to slew again the 17″ robotic...
C/2011 J2 Linear: nucleus splitting
Late last August, several observers (F. Manzini, V. Oldani, and A. Dan, Stazione Astronomica di Sozzago, Italy; R. Crippa, Osservatorio di Tradate, Italy; and R. Behrend, Geneva Observatory) noted that comet C/2011 J2 Linear was apparently showing...
Comet C/2014 E2 Jacques: a new image (31 Aug. 2014)
At Virtual Telescope we ended August observing comet C/2014 E2 Jacques on 31 Aug. 2014. The image above comes from 9, 180-seconds exposures, remotely taken with the 17″ robotic unit part of the Virtual Telescope. They were...
Comet C/2014 E2 Jacques: a new image (30 Aug. 2014)
Comet C/2014 E2 Jacques was observed again on 30 Aug. 2014. The image above comes from 7, 180-seconds exposures, remotely taken with the 17″ robotic unit part of the Virtual Telescope. They were median combined to remove...
Comet C/2014 E2 Jacques: a new image (26 Aug. 2014)
On 26 Aug. 2014, comet C/2014 E2 Jacques, we observed again. The image above comes from 9, 180-seconds exposures, remotely taken with the 17″ robotic unit part of the Virtual Telescope. They were median combined to...
Comet C/2014 E2 Jacques: a new image (24 Aug. 2014)
Continuing the close monitoring of comet C/2014 E2 Jacques, we observed it again on 23 Aug. 2014. The image above comes from 9, 180-seconds exposures, remotely taken with the 17″ robotic unit part of the Virtual...
Comet C/2014 E2 Jacques: a new image (28 Aug. 2014)
On its way back to the outer Solar System, comet C/2014 E2 Jacques is continuously changing its aspect, so at Virtual Telescope we are trying to cover it closely. The image above comes from...
Comet C/2013 UQ4 Catalina: a new image (24 Aug. 2014)
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...
