The light-curve of the comet shows features previously observed in disintegrating cometssaid Astronomer Ignacio Ferrin, from FACom, Universidad de Antioquia.
There has been a lot of scepticism and claims about the comet ISON which were greatly exaggerated, but the comet is still showing an unexpected behaviour that cometary specialists are fighting to explain.
“The light curve of the comet exhibited a slowdown event characterised by a constant brightness with no indication of a brightness increase tendency,” This slowdown began around January 13, 2013, and has continued up to the latest observations made at the end of September, this year, Ferrin said.
The brightness has remained practically constant for more than 270 days or 9 months, a behaviour without any precedent in cometary Astronomy.
These evidences has led Ferrin to conclude that it is probably that the “comet is dying”.
