    Welcome Joe!  Seems no one has replied here to your message.  
    I don't know much but found on the GlobalSecurity.org site 
    a possible 63-degree, 100 nautical mile nominal orbit,
    mentioning that this launch, originally to be from 
    Vandenberg, was then "SB-WASS - Consolidated Program" 
     http://www.globalsecurity.org/space/systems/sbwass_c.htm
    
    "The Mission-B requirement calls for a 17,000 pound payload 
    to be placed into a nominal 100 NM 63-degree inclination 
    orbit from either the Cape or Vandenberg."
    
    As you know, 100 nautical miles (115 statute miles, 184 km) 
    is very low, so I guess I would wonder about its visibility 
    from very far away.  (One would have to ask about its 
    expected duration in orbit.)
    
    See Ted's message a few weeks ago about the possibility of
    this being (or not being) a NOSS launch:
    
     http://satobs.org/seesat/Mar-2005/0294.html
    
    Here are some pages with histories of Titan launches:
    
     http://www.globalsecurity.org/space/systems/t4table.htm
     http://www.spaceflightnow.com/titan/b30/050425history.html
     http://www.astronautix.com/lvs/titan4.htm
     http://www.astronautix.com/lvs/titan4b.htm
    
    It seems that the only Titan 4 launches in 1994 appear to 
    have been with upper stages, and all were equatorial except 
    the one on May 3.
    
    FWIW, here's a French version of a Canadian parliament 
    discussion of their concerns about this launch under the 
    section, "LA CHUTE POSSIBLE DE LANCEURS AMÉRICAINS DANS LES 
    EAUX CANADIENNES - LE MANQUE DE COMMUNICATION" (terribly 
    long URL that will be broken, requiring copy-and-paste) -
    
    http://www.parl.gc.ca/common/..%5C38%5C1%5Cparlbus%5Cchambus%5Csenate/deb-F/
    048db_2005-04-12-f.htm?Language=F&Parl=38&Ses=1
    
    I do hope that some folks are able to observe the launch 
    from the northeast USA and/or Canada's maritime provinces.
