Problems: 

3:25am. Starting in image 567867 we got a warning "Error calling dtsq". Same warning appeared for the next 5 images (that is 567869-567873). Observations continued (just a warning). The transfer to observer2 was very slow, but images eventually appeared there. However, the "Delivered" buttom never got green. The DTS webpage was checked and at the time of the problem there were 17 files "Pending". An e-mail was sent to sdmops. Not sure if they did something but the problem seemed to solve on its own and starting in image 567874 the warning stopped and DTS status showed no Pending files. It is possible that images 567869-567873 were not transferred.  All images are in observer2 but those 5 images did not make it to lasrem0. SDM was informed about this and there is an entry in the eLog as well. No time was lost because of this.
