As you may remember from one of my alogs last night, i forgot to pull the FC on the witness optic in HAM3. It was decided to play it safe and pull the door to get at it. So before anyone else started in chamber work we quickly pulled the door. Particle counts in cleanroom were 10 counts and straight after the door came off was also 10 counts in chamber. Door came off at 9.09 am, Half the ISI was locked....and whilst ISI was being locked I looked at MC2 optic. Looked same as yesterday which is awesome. I tried pulling the FC on the small optic and in doing so it ripped so I only had a little bit come off with first go (I think the layer was to thin). So had to try to get at it with a gloved hand to get the rest. We did so, but it definitely meant that the cautious approach was the right one. We did a quick check to make sure we got all the FC, unlocked the ISI and the door went back on at 9.22am (off for around 13mins). Jeff checked particle counts as the door was jamming shut with the chamber and saw no puff of particulate. 

Stuart has a detailed log of timeline and particle counts that hoping he will add to this
