Just got the following notice from the TMSat team -

You know - this is asking for trouble ....

Can we split the difference?  TMSat (one of the secondaries) is supposed to
go in to an 823 km. orbit

Actually a better choice for an initial orbit would be the previous
Resurs-O1 1 launched on Nov 4, 1994.  It was also a Zenit-2 launch vehicle
(I believe IRS-1C was a Soyuz) and presumably had a similar ascent profile.
I don't have the international ID or serial number for that mission though.

I doubt it, there's all very small in the microsat category.

Here's the Surrey web site for TMSat -

FASat-Bravo is another 50 kg. class UoSat
SAFIR-2 is 60 kgs.
IRIS-1 is 40 kgs.
Techsat-2 is 70 kgs.

all fairly small secondaries.
