Subject:	TWP/TSI/C1 - solar shadowband inoperative
DataStreams:	twptsimovieC1.a1, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:	The mirror/shadowband was not turning and there was no communication with the control board. The shadowband was stuck in the position of 0 degrees from 8/29 to 9/20/2006. On 10/12/2006, the mirror was replaced, the real-time clock chip was removed and heat sinks were added to the control board, and the Ethernet hub and serial adaptor were replaced. On 1/8/2007, the slip clutch assembly, timing pulley, and timing belt were replaced (which were damaged when the mirror was replaced). These actions did not correct the problem. The instrument was swapped with the unit from Darwin so that the control board could be repaired and tested in Darwin. Several images were collected in the iterim that should be ignored. These images include periods when the sun was not masked by the shadowband or the camera lens was covered by tape to protect the CCD from direct exposure to the sun. There are also extended periods of missing data when the instrument was shutdown, waiting for parts.

Subject:	TWP/TSI/C2 - hazy image
DataStreams:	twptsimovieC2.a1, twptsicldmaskC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1
Description:	Condensation in the camera lens and/or filter caused the sky images to be "hazy". The desiccant in the main enclosure was changed and the neutral density filter was cleaned.

Subject:	TWP/TSI/C1 - hazy image
DataStreams:	twptsimovieC1.a1, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:	When the TSI from Darwin was installed (so the instrument from Manus could be returned to Darwin for repair) moisture in the camera lens and filter caused the sky image to be very "hazy". The U10 chip was removed from the control board, desiccant was installed inside the enclosure, additional small desiccant bags were installed inside the camera housing, the camera housing was sealed with silicon to prevent moisture ingress, and the camera lens filter was cleaned and the focus adjusted.

Subject:	TWP/TSI/C2 - Mirror continuously rotating
DataStreams:	twptsimovieC2.a1, twptsicldmaskC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1
Description:	The mirror began to continuously spin. Diagnostics were performed on the encoder, control board, and Ethernet adaptor. The instrument was removed on 1/2/2008 and shipped to Darwin for repair. The encoder and control board were replaced and the instrument was reinstalled.
