After a lot of uncertainties in the last days the decay - predictions for 
PEGSAT, 1990-28A (SSC 20546), are now more consistent. Our Multi Parametric
model (MPM) based on the three elsets of day 316 give this estimate:
                        Nov 14,  05:48 UTC
That is on the northbound pass just before equator passing (Long. of Ascending
Node 0.7E). The elset from this morning (UT) shows a slight tendency to shift 
the decay to one rev later (07:15 UTC). But let us wait and see the next elset.
