Between yesterday and today, Gerardo and I (well mostly Gerardo, I just spot checked and helped with calculations) successfully bonded an ear onto the S3 flat of ETM11.  The ear is s/n 188.  By successfully, we mean that the surface area coverage and post-bond locational dimensions meet the spec.

We had an interesting find when we opened the optic can this morning, however.  Upon dismantling the cake tin container from around the ETM11 as usual, we lifted the oring plate off of the AR surface and found one of the inner handle screws was left sitting upright on the surface of the optic.  It must have spun loose during shipping and jostling around the lab.  SYS/COC have been alerted to this failure mode of the container.  This is the first optic we have started to process which has no first contact on it after long-term storage in the container.  After carefully removing the screw, I inspected the area and miraculously could not find any macroscopic marks or scratches.
