No beam from start of maintenance day until about 8am this morning.
Currently: tuning the beam to the tagger dump.

Yesterday during the maintenance day the target group switched the target from NH3 to ND3, after having established a polarization signal on the deuterated butanol target See: https://logbooks.jlab.org/entry/4011974, https://logbooks.jlab.org/entry/4011923
Current polarization as reported by the target screen fluctuates around 4%

Plan:
* Establish beam to the hall.
* Work with the target group to increase the target polarization doing cold target irradiation.
* Take data on ND3 if target polarization is acceptable, otherwise switch back to NH3 before the weekend.

We will have an RC meeting today at 2pm EST.
