Marginal (HRPT received, Partial GAC received)
Antenna was tracking vehicle during GAC, but lost frames a quarter way through the downlink. Could not re-establish a connection to sync onto GAC. HRPT was established after GAC was finished. Operators reset modem after contact and reached out to Parsons's team to monitor the 17:14z contact.
