Robots were homed, exposures aborted, and the FPS was turned off. I discovered at the telescope that the same glycol leak had returned, and with a vengeance. It leaked all over the 15-degree stop, inside an electrical socket, and pooled underneath the telescope. The chiller switch was turned to 'off'.

My decision was to remain closed for the remainder of the night, given the amount of pollen in the air and the unlikelihood that a repair could be done with the few hours that remain in the night.

Looks like the patch didn't last long.  Yesterday I found just enough
hose to bypass the leak re-using the connector Ryan and I used the last
time.  More are on order, but they won't be here until tomorrow (along
with more hose).
Should be running again tonight.
