    Here are two more passes of northbound sun-synchronous satellites. 
    Both were found while trying to get more obs of previous unids. 
    The 000405 satellite is higher than the others (about 1160km if 
    orbit is circular).

    The 000406 satellite is about 700km, and is consistent with RE's obs
    of 000404, here are two orbits which fit both passes well (sorry no
    check digit):
