The lower orbit wasn't connected with Progress M-32 launch because these
spacecraft are often launched by Soyuz U. The real reason is that Soyuz TM-24
manned spacecraft is to be launched Aug.14 at Soyuz U also, instead of
usual Soyuz U2. They have mass deficite of approx. 275 kg. It was found that
one way to solve the problem is to rendezvous with Mir at lower orbit.
The orbit was lowered July 2 and July 4 (maybe more).
