Notes from the 4PM Meeting

A new set of JSONs are sent in to the mountaintop. It's the GW stuff minus the LMS exposures. TOO observations would start at 6:29 UT (3:29 local). 10 minutes early on the TOO. Up to 10 minutes before the TOO let a short SN sequence start. If it's a long sequence stop OBSTAC and start the TOO early. GW is propid 2015B-0187. Hopefully we finish C3z; priority over TOOs.
