The North American Aerospace Defence Command was tracking the debris, estimated to be about the size of a school bus, after 10 a.m. local time on Friday. At first the debris was set to fall in Calgary, but officials later determined it would strike near Kneehill or Wheatland County, about 100 kilometers east of Calgary." The article continues to say that the debris ended up in the Atlantic Ocean. I'm simulating a 56° alt southward pass of Iridium 33's impact-epoch elements over Calgary at about that time. Note that the impact epoch was a few days ago and anything fallen from a circular Iridium-altitude orbit will have spread out from the original time of pass. Possibly this is connected with a note I read on spaceweather.com to listen in to US Air Force Space Surveillance Radar from Lake Kickapoo, TX at about midday today. Now there is another note there to listen between 2:18 and 2:28 am CST (0818 - 0828 UT) Saturday morning. Looks like that corresponds to a southward pass of the Cosmos 2251 elements. The Progress SL-4 RB was at zenith in Calgary at 10:42 AM CST using elements from Celestrak. The incident is likely from the SL-4 RB. Chatter about this seems nonexistent except on some Canadian mass media such as the Lethbridge Herald, http://tinyurl.com/cdh6j9 note "Alberta Municipal Affairs would have warned the public not to touch any debris on the ground because it could have been radioactive." Once bitten twice shy for anyone who remembers Cosmos 954.
