    I would like to thank all colleagues for their help to identifying the
    satellite. It was really a surprise for me to find that other satellites
    besides the Iridiums can produce so bright flares.
    I found very interesting the history of the evolution of ERS1 posted by Ted
    Molczan, caught my attention that in the field of satellite observation
    enthusiasts and amateurs can contribute consistently with information of
    scientific relevance. And it encouraged me to create a personal program of
    observation of this satellite (basing on the excellent  informations of the
    site "") to begin.
    Finally I would like to ask: what can be considered the best "desktop
    Planetarium" (more precise and which allows automatic and/or manual updating
    database of satellites) for tracking satellites?
    Best Regards
