It's also worth noting that a similar phenomenon apparently appeared over China back in April 2009:
We're still betting on some rocket test gone awry, or else a really far-out art display by a guerilla artiste with a penchant for science. Inter-dimensional research or the beginning stages of an alien invasion remain farther down the probability list.
