It's associated with the Falcon 9 engine firing that produced the orbit prior to releasing Globalstar - either the actual firing or venting of residual gases immediately after. The satellite was released at 06:20 UTC, shortly after reaching your horizon:

Your reported Az/El is close to a predicted sky track based on the Globalstar orbital elements released so far.

One circuit later you would have had a near-zenith pass of Globalstar itself centered on 08:02 UTC but the Falcon 9 had re-entered about 20 minutes earlier.
