    That has happened with previous Molniyas. They may also lose solar panels
    etc, which delays their decay. As the number 3-44 implies there are lots of
    them - Nov.2003 Satellite Situation Report list 163 (+6 debris) under the
    Molniya name. 99 of the satellites had already decayed then. The perigees of
    the (successful) Molniyas are close to the southern apex.
    
    Alan Pickup alerted SeeSat-L on this decayer in a mail on Jan.04
    http://www.satobs.org/seesat/Jan-2004/0045.html, and again on Jan.21
    http://www.satobs.org/seesat/Jan-2004/0191.html and his web page
    http://www.wingar.demon.co.uk/satevo/dkwatch/ had updated elements. I was
    also able to get fresh elements from OIG before I went to look for it, and
    found it 67.1 s early on the 10.5 h  old elset Jan.22
