According to my model, some NOSS satellites can generate peculiar flares that may reach the negative magnitude (down to -2) and that can last even for one minute or more. This is due the right combination of the satellite movement and tilting along the orbit. The combination can make the flare spot quasi-stationary on the earth surface for some time. In addition, the satellites can flare when their elevation is quite low and this might give to the observer the impression of no motion until they disappear completely. Nevertheless, ordinary flares, that reach the negative magnitude, could be quite nice as well because of the pair formation.

Example of a stationary flare
The following pictures show the satellite at a stationary flare time. (Click on the image to zoom in).The event occurs when the satellite is in the south-east part of the local sky.
