Let's move onto vsnet-chat. The exactly same kind of discussion was what we experienced (with our domestic observers) when we encountered the giant second outburst of V838 Mon. That outburst was then referred to as an accidental explosion of a spacecraft from the star GSC 4822.39 heading toward earth ;-). The "hypernova" signature of GRB 030329 was also referred to (by the same people) as a catastrophic explosion of a highly evolved ET intelligence which attempted to send a signal (and crashed ;-) to earth upon the appearence of a bright GRB. # Yamaoka-san is said to have been searching for a signature of remnant of # such an explosion on Kyoto images of this GRB...
