| Content: | Toshi, Thanks for watching our performance. 1. We were in the process of shipping a timing system there, as we identified the problem last Sunday. Our hardware shipment can only be done on the following Monday and takes 2 days to get to Hawaii from Washington. 2. While waiting for this hardware to reach the station, the crew took data thus biasing the system. 3. We shut down operations until the shipped hardware reached the station. 4. As always, your service is highly appreciated.
