Gas Cloud Wiki
This page collects useful information for researchers interested in the gas cloud 'G2', discovered in 2011 by Gillessen et al. G2 is falling currently towards Sgr A* on a highly eccentric orbit, with a predicted pericenter epoch around September 2013.
There is an email-alert list. The archive of this list is
