Comet C/2012 S1 Ison: new image from the Virtual Telescope
Comet C/2012 S1 "Ison": 4 Mar. 2013
Comet C/2012 S1 “Ison” is expected to be a potentially amazing comet later this year. While it continues its journey to the inner Solar System, it is monitored by many astronomers around the planet and the Virtual Telescope team is doing the same.
The image above comes from the average of 5 single exposures, each integrated for 300 seconds. For this, the PlaneWave 17 robotic unit was used. The telescope tracked the stars without any autoguiding. A little tail is clearly visible.
We do expect to keep an eye on this comet for the next months!

Hallo Gianluca, how can we estimate the dimension of this comet in particular?
Which is the fact that leads us consider it will be very bright? thanks
The orbit and the perihelion distance are the most important factors. Of course, being a comet, there is still a lot of uncertainty on the real behaviour
