Comet ISON, formally known as C/2012 S1, was a sungrazing comet discovered on 21 September 2012 by Vitaly Nevsky (Виталий Невский, Vitebsk, Belarus) and Artyom Novichonok (Артём Новичонок, Kondopoga, Russia).
He also discovered the periodic comet P/2011 R3 (Novichonok) in 2011, and he was part of the group that discovered the hyperbolic Comet ISON in September 2012, with Vitaly Nevsky at Kondopoga, Russia.

Sungrazing comet

Comet ISON, formally known as C/2012 S1, was a sungrazing comet discovered on 21 September 2012 by Vitaly Nevsky (Виталий Невский, Vitebsk, Belarus) and Artyom Novichonok (Артём Новичонок, Kondopoga, Russia).
However, comet C/2012 S1 (ISON), which disintegrated shortly before perihelion, had orbital elements similar to the Great Comet of 1680 and could be a second member of the group.

Coma (cometary)

However, later that day CIOC (NASA Comet ISON Observing Campaign) members discovered a coma-like feature, suggesting a small fragment of it may have survived perihelion. On 11 August 2014, astronomers released studies, using the Atacama Large Millimeter Array (ALMA) for the first time, that detailed the distribution of HCN, HNC, H2CO, and dust inside the comae of comets C/2012 F6 (Lemmon) and C/2012 S1 (ISON).

International Scientific Optical Network

ISONISON-Kislovodsk Observatory
The discovery was made using the 0.4 m reflector of the International Scientific Optical Network (ISON) near Kislovodsk, Russia.
It was credited for the discovery of comets C/2010 X1 (Elenin) and C/2012 S1 (ISON), the latter popularly known as Comet ISON.

BRRISON

On 28 September 2013, NASA launched BRRISON, a stratospheric science balloon carrying a 0.8 m telescope and science instruments designed to capture images and data on Comet ISON from an altitude of 37 km.
The Balloon Rapid Response for ISON (BRRISON) was a NASA project involving a stratospheric balloon with science instruments intended to study comet C/2012 S1 (ISON) and other celestial objects.

C/2013 R1

It had an appearance similar to comet C/2013 R1 that was also visible to the naked eye.
It became more impressive than comet ISON.

HCN, HNC, H 2 CO, and dust have also been observed inside the comae of comets C/2012 F6 (Lemmon) and C/2012 S1 (ISON).

It had since exhibited a "slowdown event", however, similar to behavior exhibited by other Oort cloud comets, among them C/2011 L4.
* C/2012 S1 (ISON) – a highly anticipated comet that disintegrated near perihelion in November 2013.
