Any kind of blast or flare coming from the galatic core has the potential for some serious ramifications here on earth. If you recall a pulse from the galatic core is still possible from that G2 cloud floating near the core as well. This is a small update. jopipe
Warning: Today a Swift X-ray spike alert was sent out. An abrupt spike in X-ray emission was detected today coming from the Galactic center, Sgr A*. This spike is the largest to occur in the past year and a half. The X-ray spike that occurred 500 days ago came from a magnetar near the Galactic center. Whether the current spike is being emitted by this same magnetar or is coming from the Galactic center itself, we can’t be sure until further data is obtained. Because it appears to have been a brief event, the X-ray signal coming back down to its previous noise level, my guess is that this is coming from the Galactic center, possibly due to a discrete object falling into the core. Tomorrow’s Swift data will show whether the low X-ray emission continues or whether it soars upward again. Let’s pray that this September 11th will not bring to the world any serious danger. For the time being, to be on the safe side, we should begin taking precautions for possible successive events of elevated cosmic ray exposure event.
Keep in mind that this is a very small spike that would not have posed any cosmic ray exposure hazard. When it becomes a thousand fold increase, then we have some cause to worry.
