Plan for the next 24 hours: 
- Will flip the HWP later in the swing shift. Bill Henry from  Hall A has offered to help us optimizing the beam charge asymmetries when we change the HWP. We will call him and he will stop by to run his code for a minute. 
- uRWELL folks may need a rapid controlled access to the hall for 10-20 minutes to fixe a loose connector issue (not confirmed 100%).
