Dear all,

Thanks! I posted a follow-up log entry (https://logbooks.jlab.org/entry/4415279)

I also informed the shift crew and they will call me if there is an access opportunity (I said more than an hour of expected downtime), and I will let you know if so.

Cheers,
Chris

Hello,
I agree with Valery, no reason to stop the data taking, but in case
please be ready.
Thank you,
Marco
