Entry Makers: bschaumlBody: 

2L09-1 tripped off and needed an open loop tune. The recovery was fairly standard but the only noteworthy things were that we needed to clear the hardware driver for the tuner which was showing an error.

After recovering the cavity, we found that we couldn't make it up the 2S ramp and needed to goose up 2L19, the SL energy lock zone, up about 11 MV/m to get around the arc. To keep the wheels on the bus while we were figuring things out we decided to fudge and reLEM, bumping the fudge factor up by 17.
