CU Professor Dr. Shelly Miller and graduate student Josue Hernandez Pedroza have done some testing. But the main testing protocol is scheduled to begin on July 25. The delay has been caused by the smoke from the Nederland fire and the need to complete off-site calibration of the instruments. Thanks to a "matching contribution" from Google, we now have raised $5050 - exceeding our goal of $4500. This will enable us to do more extensive testing. Thanks VERY much to all contributors.
