Isaac arrived at ISB at 9:47am. The doors to the collector had opened and there was a sample in the collection jar. The sample appeared clear with a small amount of sediment in the bottom of the jar. The sample was then removed and placed in a labeled bag. The collector was then disassembled and its components were cleaned with 409 and DI water. The collector body was then cleaned with 409 and DI water as well. The collector was then reassembled with the cleaned components. Upon reassembly a blank was taken by spraying the string frames and allowing the DI water to drain into a newly placed jar. This blank was then removed and placed in a labeled bag. The system was then reset for the next fog event.
