So "mid to late 2013" - almost the time, are there any new observations yet?

Predictions of its orbit suggest it will have a closest approach to the black hole (a perinigricon) in mid to late 2013. At this time the gas cloud will be at a distance of just over 3000 times the radius of the event horizon (or ~260 AU, 36 light hours) from the black hole. Opinions differ as to the effect this might have on both G2 and the black hole.

A star being torn apart in the center of our Galaxy is significant because it provides valuable insights into the dynamics and structure of our Galaxy. This event, known as a tidal disruption event, can help us better understand the supermassive black hole at the center of our Galaxy and the surrounding environment.
A star can get torn apart in the center of our Galaxy due to the strong gravitational forces of the supermassive black hole. As the star gets closer to the black hole, it experiences extreme tidal forces that stretch and tear it apart. This process is known as spaghettification.
The material of the star is heated and accelerated by the intense gravitational forces as it falls towards the black hole. This results in a bright flare of radiation that can be observed by telescopes. The material then forms a disk around the black hole, known as an accretion disk.
Tidal disruption events, where a star is torn apart by a black hole, are rare events in our Galaxy. It is estimated that only one star is disrupted by the supermassive black hole at the center of our Galaxy every 10,000 years.
Studying stars that are torn apart in the center of our Galaxy can provide valuable information about the properties of the supermassive black hole, such as its mass and spin. It can also help us understand the physics of extreme gravitational forces and the formation of accretion disks. Additionally, these events can serve as a powerful tool for studying distant galaxies and their central black holes.
