Hello,

When I noticed the light flashed in my office, I checked and found that the
magnet tripped again at 17:46.
This time, it was due to a major power dip (that RHIC still can't fill to
make up a store).

After the Cryo group informed us that the Cryo has recovered, I drove back
from home to 1008B mezzanine to
push that button for closing the contactor, as the CAS was busy with many
other works due to the power dip.
I brought back the magnet to the top current again at 22:37. Hopefully,
it'll stay there for a bit .... ☹ 😊

I attach the plot of magnet currents, water-cooled-bus temperatures and cryo
temperatures.

Kin
