HWSX alignment recovered
Betsy, Nutsinee, Aidan(on the phone)
The outgoing beam appeared to be clipping at the top periscope. After 2 hours of adjusting the periscope mirrors alone we couldn't make progress. Aidan suggested that we unbolt and move the top periscope mirror so we tried that. This gives us more room to point the outgoing beam where it needs to be pointed and recovering wasn't difficult after that.
THe Hartmann plate was put back. The code has been re-initialized. Started writing data at 20:35 UTC.

The number of spots (604) is reasonable. The peak count average is 416 - which is a little low.
The RMS on the spherical aberration is very high. Once I get my Yuibkey working again, I'll log in and check the spot distribution that the code is exporting.
