These 2 IBX-CLC-006 soft violations are acceptable. The 2 contacts are as follows:

USAK01,03/18/20,078,15:00:00,03/18/20,078,16:00:00, 160K IBEX-3 Orbit# 480 SSR_Dump/Tracking Contact 14re Asc

The is a 3 hour gap between the 2 contacts. This will give the transmitters plenty of time to cool down. Also, the transmitter temp is a point that we routinely  monitor.
