Subject: | TWP/TSI/C1 - hazy image |
DataStreams: | twptsiC1.00, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | Moisture in the camera lens and filter caused the sky image to be very "hazy". The lens and filter were cleaned, the moisure seals were checked, and desiccant was added to both the camera housing and main electonics enclosure. |

Subject: | TWP/TSI/C1 - moisture in camera housing |
DataStreams: | twptsiC1.00, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | Water infiltrated the camera housing after periods of heavy rain causing moisture to collect inside the neutral density filter, corrupting the images. The filter was cleaned, o-ring seal checked, and camera housing sealed where it joins the arm. |

DataStreams: | twptsiC1.00, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | The TSI at Manus has been able to remain dry and produces an image but the percentage of cloud cover is determined to be 100% even on cloud free days. Moisture in the camera lens and neutral density filter was corrupting the sky images. The lens and filter were cleaned, the moisure seals checked, the camera housing sealed, and desiccant added to both the camera housing and main electronics enclosure. On 3/23/2006, the lens was replaced and the sky images were significantly improved. |

Subject: | TWP/TSI/C1 - high control board temperature |
DataStreams: | twptsiskycoverC1.b1 |
Description: | The TT8 control board temperature was high, ~50C, so that the cooling fan was constantly on. It appears that the heat sinks were not transferred from the original board to the new one when it was replaced. The problem was corrected when heat sinks were installed. |
