What I meant was that if Lacrosse 5 keeps a local attitude (pointing with one side always toward the center of the Earth and with another side always into the direction of flight) than within this local satellite coordinate system the sun would have moved by just 1 degree over the seven minutes of observations starting at 20:12:15 UT, 14-AUG-07. During that time the angle between the sun, the satellite and an observer on the ground would of course change much more. What is interesting about Lacrosse 5 is that there have been at least two cases where two or more observers at locations hundreds of km apart have seen a sudden (within two or three seconds) decrease in brightness of that satellite at exactly the same time (while the satellite was still lit by the sun of course). We are still at a loss of how to explain this.
