    Friends, just a reminder about the rule against posting Space Track data to the
    list.
    
    At least several countries operate space surveillance systems, but the U.S.A.
    remains the only one that publishes the bulk of its data. It is a great
    resource, so we should comply with the rules against unauthorized
    redistribution.
    
    I made this rule soon after Space Track began operations:
    
    http://satobs.org/seesat/Jan-2005/0093.html
    
    and have added it to the Rules and Guidelines page:

    Do Not Post Elements Originating from Space Track
    
    When posting to SeeSat-L, you must comply with Space-Track.org's user agreement,
    by not posting elements or other data, e.g. RCS values, that originated from
    that site. This SeeSat-L rule also includes elements of unclassified objects
    obtained from NASA/OIG or third parties - even those who have Space Track's
    permission to distribute elements, since it is almost impossible to later prove
    how the data was sourced. This applies also to historical elements, since most
    of those now are also available from Space-Track.org.
    
    Where past practice was to include an elset of an unclassified object to
    substantiate an argument, now it is best to state only its name, international
    designator, catalogue number and perhaps the epoch or serial number of the elset
    in question, and leave it to interested readers to obtain the actual elset, or
    include a link to a source.
    
    I appreciate your cooperation in this matter.
