DES:
Earthquack caused observation stop and telescope/instrument check. Lost 1h.
DECam NB project:
Image 515770 (900s exposure with N964) is not a good exposure: it was observed with only single star guiding, then the guider lost ~1-2m before the exposure finished (Alarm ID 2300: DECam_201602 Continuous null centroids limit exceeded). We corrected the telescope poing 30s before the exposure finished (with center command, Correction: RA offset 19.4, Dec offset -17.8), but seems like the pointing jump is happened immediately, not after the current on-going observation. There were tiny companions located at the top-right of each bright stars in the image 515770. The distances just matched the offset-correction.
We took new images of SN 2016adj in Centaurus A (FID: 515790--515805) in ugrizY bands.
