While we understand why SP2's 10 liter ran dry last night, we still do = not know why the SP1 180 liter lost it's full 100 lbs between 5 pm and 6 = pm yesterday. Dan does not think the two are related, so even if we are = closed all night it would be a good idea to monitor this closely in case = it was an actual fault rather than a non-recurring accident. Drive surfaces and fiducials cleaned and fiducial read checked today. We will try to take a fiducial data set tomorrow morning. If it is at = all possible to ventilate some time tonight that would be very helpful, = as we are not sure the fiducial set will be worth using with the lower = enclosure several degrees above ambient. Roof leaks noted in the SE and SW corners of the enclosure. Absorbent = pads were put down where it's dripping. =20=
