    Hello Marco,
        Perhaps it is time to adopt a coordinated approach to observing
    Lacrosse 5. Would it be possible to attempt observations from multiple
    sites so that L5 was observed from different angles simultaneously and
    along its track consecutively? Pooling the observations of flares and
    fades could lead to producing a silhouette of the satellite. Even
    negative reports may be useful. Such an undertaking would require the
    cooperation of many members.
