|
| 02/05/2006 | 04:48:00 | CHANNEL 01 | HIRS long wave channel noise continues to occur intermittently sometimes lasting for several days even in the absence of solar array moves and other potential perturbations to the loose LWIR lens cover. Channel-1 most affected. |
|
| 01/04/2006 | 12:00:00 | CHANNEL 01 | Because of improvements in the long wave channel noise situation and an understanding of its causes (loose lens cover), N18 HIRS has been upgraded to Green status. |
|
| 12/15/2005 | | CHANNEL 01 | TOAR board investigation concluded on HIRS long wave channel noise. Problem attributed to loose LWIR lens cover that is highly sensitive to minor spacecraft attitude purturbations such as solar array offset changes. Channel-1 reported as nominal although channels 2, 4, 5, 6, 7, 9 and 10 are reported as somewhat out of spec. |
