Swift is finally back online after a lapse of almost 3 months. For what reason? They do not say. Things still look quiescent at the Galactic center as of February 6th. The G2 cloud has long passed its pericenter andthere have been no signs of enhanced activity other than the brief spike around September 10th. As I had predicted last year, no activity should be expected from the Galactic core due to the expected infall of gas and dust stripped off from the G2 cloud because the cosmic ray wind from the Galactic core is so strong that such gas and dust would be blown away from the core. The only activity expected would be from bodies such as comets or planets tidally stripped off and slowing down sufficiently to fall into the core. So far such infall events have not been observed. This X-ray chart will be updated on an approximately monthly basis, unless there is an activity alert.
At this point the general consensus of astronomers is that the G2 cloud contains one star. As stated before, the unanswered question is whether if the G2 cloud contains a star with a planetary system and if the Galactic core is able to tug comets or planets away from the parent star, whether hydrodrag effects of the core's ion and cosmic ray wind will be sufficient to cause such bodies to spiral into the core and trigger energetic activity. This possibility has been explored in the May 19th posting. Currently, there is little chance that the G2 cloud system will trigger a superwave outburst.
Keep in mind that we should always be prepared for the occurrence of any unexpected space weather event.
