Did a little steering to straighten out their orbit. Viewers look good enough so we'll send them their 5 nA and see what the harp swipes look like.

Day shift passed down that the 2T orbit did not restore as we would hope. Due to the immense sensitivity of optics to steering in this region I figured I would take the time while the Hall was down to get it as close to where it was when optics was deemed acceptable. The relative orbit that I steered to was captured with tune beam to the 2C04 dumplet. Figure 1 shows beam as found to the 2C04, 2 beam as left, and 3 the corrector changes to get there. Figures 4 and 5 show the harp scan from after the steering and before owl shift optics tuning on the 11th.

Figures 1 and 3 before maintenance, figures 2 and 4 after. Height unchanged. Width is likely the same given the beam motion evident in figure 4.
