DataStreams:olitsiskyimageM1.a1, olitsiskycoverM1.b1, olitsicldmaskM1.a1
Description:
The TSI mirror became loose from the shaft due to high wind. The lens was covered from 5/1 
00:25 to 5/2 22:07 to protect the CCD. The mirror was secured to the shaft on 5/8 and 
TSI Tracker was ran on 5/19 to correct the lat. and lon. and reset the home (north) 
position of the mirror. The lat. was also corrected in TSI Manager on 5/19.
