| Subject: | SGP/SIRS/E9 - Tracker failure |
| DataStreams: | sgpsirs20sE9.a0, sgpsirsE9.b1 |
| Description: | The solar tracker was not functioning during these periods. During both failure events PM found the solar tracker in its parked position. PM reset the tracker and it resumed normal operations. Data from instruments directly reliant on tracker operations (short_direct_normal, down_short_diffuse_hemisp) are not recoverable. The longwave data should not be affected. |
