This morning, TJ and I took FTIR samples of aras around the HAM5 OFI KTP burn event area and the HAM6 Fast shutter suspicious heat mark.
Report (and eventual results) posted to: https://dcc.ligo.org/E2400268
Relative Humidity reader on the table inside of HAM5 was reading 5% when we got in, 9% an hour into work with the cover open, 2 people.
