Interesting observation! One or two more observations of same or better brightness, in other directions, may fix the rotation axis. I found one by Jim Nix from Sep.02, but precession may have changed the axis considerably since then. The period may be 6.67 sec, but then the second series is only 0.7 sec before the first. 2.22 sec would be expected from different MMAs if the rotation axis was along the long axis - but I guess the greatest moment of inertia is at right angles from this. It is possible to fit the two series to a reflection from one surface, with a period of 6.63 seconds, and it is geometrically possible since the flashes trace en "ellipse" on the hemisphere, and the "straight" track can intersect this twice. -- bjorn.gimle@tietotech.se (office) -- -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- -- COSPAR 5919, MALMA, 59.2615 N, 18.6206 E, 33 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- -- SeeSat-L / Visual Satellite Observer Home Page found at -- -- http://www2.satellite.eu.org/satintro.html -- Don Gardner wrote: > There was an interesting pattern of bright flashes from Iridium 27.
