Subject: | GRW/TSI/M1 - Shadowband Misalignment |
DataStreams: | grwtsiskyimageM1.a1, grwtsiskycoverM1.b1, grwtsicldmaskM1.a1 |
Description: | The shadowband was intermittently misaligned and not completely masking the sun because the mirror became loose from the shaft while being polished. The shadowband was realigned on 1/14 but by 1/27 was again slightly misaligned. The instrument was reoriented with true north on 1/27 and the shadowband adjusted again on 1/31. The problem was corrected on 2/2 when the mirror mounting was tightened and the shadowband realigned. |
