    Although it seems clear that a sun-synchronous orbit is not in the cards, I 
    wouldn't rule out the 88.7 degree orbit. We're kind of one-for-one on the polar 
    vs "solar-sychronous" claims, as the first announcement that came out on March 
    16 said, "Kwangmyongsong-3, a polar-orbiting earth observation satellite, will  
    be blasted off southward from the Sohae Satellite Launching Station in  Cholsan 
    County, North Phyongan Province between April 12 and 16, lifted  by carrier 
    rocket Unha-3. A safe flight orbit has been chosen so that carrier rocket  
    debris to be generated during the flight would not have any impact on  
    neighboring countries."
    While the more recent sun-synchronous claim is false, it's also not backed up by 
    other such claims that I know of and could be a slip-up of unknown etiology. In 
    any event, getting ready to look for something in an 88.7 degree, 500-ish km 
    orbit would be worthwhile, IMO. If nothing were to show up after an apparently 
    successful launch, that would definitely indicate some skulduggery.
