 The potential for skin seeing at PS1 is being investigated in two ways. A temperature monitoring system has been installed and series of seeing measurements has been initiated.
+
+=== _Dual RoboDIMMs August 25, 2010_ ===
+
+The RoboDIMMs were set up south of PS1 so they point at Polaris along the west side of the dome. To get the star to appear just off the widest part of the dome I placed the DIMMs about 20' off the road in the area leading to where the ATST tower used to be located. To locate the DIMM measuring seeing near-dome I moved the DIMM east until the images were blocked by the dome then moved it west until they were just clear. The other DIMM was placed 5' to the west.
+
+During the time the data was collected the dome was basically stationary while the observer, Natalia, was taking pinhole data on the moon. Because the moon was rising the near-dome measurements were made off the surface of the rear shutter.
