Hi All,

I have observed the erratic Iridium 11 on two consecutive evenings, and 
believe I have discerned a "pattern" (for lack a of better word).

On the 16th, it passed to the east of my location and had some bright 
flashes before it culminated (+1.0). They  were seperated by 5-6 

On the 17th, it passed west of my location and also had some bright 
flashes (brighter: -2.0) , again before it culminated.

Much fainter flashes  (+6.2) occured after culmination on both nights.
