Queso Posted March 23, 2006 Report Share Posted March 23, 2006 Tunguska Russia meteor/comet airburst event of 1908.:hihi: Really? Where'd you obtain that knowledge, man? :hihi: Amazing that you would know something like that! Quote Link to comment Share on other sites More sharing options...
Buffy Posted March 23, 2006 Report Share Posted March 23, 2006 Where'd you obtain that knowledge, man? :confused:Turtle knows *everything*!!! But seriously, if you like History or Discovery Channels, its hard to avoid running into a program at least every other month that talks about the Tungushka "event"....

Buffy Posted March 23, 2006 Report Share Posted March 23, 2006 I'll quibble with Turtle's conclusion though: If you look at the graph, although there's a local minimum at 1908-9, the 5-year moving average seemed to start at 1900, which predated the event. Who knows what method they used to compute the 5 year average (it could be the 5 years around the event, which means that specific events effects would be hidden, or 5-years back (which is what most, but not all, computations use). Back to the history timelines... Someone might want to check the 11-year sunspot cycle which is normally highly correllated with such data...
