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: http://satobs.org/seesat/seesatindex.html#NoSpaceTrackData 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.
