We recovered well from beam maintenance day, and received the production quality beam around 9-10 pm last night. The harp scan looked good

Carbon hole check: https://logbooks.jlab.org/entry/4410556 , hole looked higher but still within the rectangle.

Production running resumed around 11pm, and smooth beam delivery overnight. There was a DAQ related issue around 5am. The VPN terminal froze. The shift crew started the local coda computer ,and kill/restarted CODA. The issue was resolved. Lost about 20 mins of beam time.  

Looking ahead, accelerator goes down ~8:30am this morning for a turbo replacement, and is projected to be down for 4 hours. We expect to enter production mode directly after beam recovery. No change of beam or running condition into the long weekend.

We will have the daily meeting today at 2:30pm.
