HWS alginment in the corner station.

Dave O, Greg, Elli

Yesterday we tried to realign the Hartmann sensors in the corner station.  This is because 14-11-12 17:15:00 the SR3 mirror changed alignment which threw out the HWS alignment.  We found the alignment is now so bad the periscopes will have to be moved.  I still need to do this.  If the alignment of the SRC, BS, or ITms changes again we will have to realign the HWS again.

Are there any photos of the current positions of the green beams at the HWS periscopes?
