Most recently, there was a
post about the comet ISON, which, according to forecasts, should be visible with the naked eye at the end of the month. However, quite recently, a comet sharply increased its brightness, which allowed seeing it not only to many earthly observers, but also to space solar observatories.

Now the comet can be observed, without leaving the house, through the Internet, thanks to the space solar observatory STEREO:
WikiTotal grouping of satellites consists of two devices: STEREO A and STEREO B.
The comet appeared in the field of view of the apparatus in the middle of October, but then it was a very dim object, and I will give an animation of its movement at that time:
Then its brilliance was about 10
m . But now its brilliance has increased to 5m for the earth observer and about the same for the observatory chamber.
Here is an animation of the rapid increase in comet brightness:
How to trace the life of a comet?
We go to the repository of images of the STEREO observatory by the link of the form:
http://secchi.nrl.navy.mil/sccimages/HI_A/YYYYMMDD/1024/Where YYYYMMDD is today's date, HI_A is the name of the device (in this case, STEREO A, for STEREO B - HI_B).
Accordingly, the archive for November 13 will have a link:
http://secchi.nrl.navy.mil/sccimages/HI_A/20131113/1024/ (Publication in the archive is 4-3 days behind)
Next we have a large list of shots, we need camera number 2, so we choose pictures whose name ends with A2.
As you may have noticed, the title of the pictures shows the time of shooting.
How to find a comet
And here the recommendations on the page of the observatory will help us:
http://stereo-ssc.nascom.nasa.gov/comet_ison/At this time, the comet is visible in two cameras, I will give maps of the paths of comets on these cameras (ephemeris step - 1 day):
HI2-A. 10-10-2013 (left) to 23-11-2013 (right)

HI1-B. From 24-10-2013 (right) to 25-11-2013 (left)

However, in the near future (in a week and a half) the comet will enter the field of view of the coronagraph cameras, by which time it will heat up well and the tail will be visible, as Comet C / 2011 W3 had in December 2011:
The path of the comet ISON in sight of LASCO C3 and C2 on November 27-30.
Finally
Of course, modern technologies make it possible to observe the most interesting astronomical phenomena, not just without leaving home, but even without getting up from a chair. However, as an observer with experience I want to say - at the slightest opportunity, get out of the country and observe with your own eyes this miracle, show it to your near and dear ones. After all, it is from visual observations remain the most indelible impressions of a lifetime!
Good luck!
