---++ Agenda

   * Status report from Bonn-Shutter.   Level of completion:
        - What design work remains?  
        - What parts are in fabrication?
        - What procurements have been received 

   * New test results, if any from Bonn-Shutter.   Tests pending.

   * Shutter blades: (Bonn-Shutter)
	- Design properties (impact and wind resistance; mass)
	- Procurement status.    (Has a vendor been selected)

   * Report on last round of telescope tests. (R.Smith)
	See frequency response plots below.   Full report is pending (still).  Need to add averaged impulse response. (We have the data.)
	Discuss whether vibration isolation is required at shutter interface
