Problems: 

Cirrus: blurgh! 

One hardware shutter error @ 02:57 (UTC). This crashed the DECal scan, which in turn, lead to several other DECalS failures mostly associated with LabView, and curiously one failure of the IP-addressable power strip. about one hour lost in total.

p.s. DO **NOT** PAUSE A DECAL SCAN (on the DECalS machine), THE LABVIEW SOFTWARE CANNOT RECOVER AND HANGS.

Comments: 

Thickish cirrus all night, stay closed. DECal scans taken.

(1)  Coarse, no-filter scan across the entire far-UV, optical and near-Ir wavelength range (300-1100nm), 10-nm bandwidth, 10-nm steps; dark exposures every 5-images. 



First image is DECam_00394792 (@300-nm)
Last good image was DECam_00394872 (@965-nm)

shutter error and DECal crash

re-commence:
First new image is DECam_00394879 (@950-nm)
Last new image is DECam__00394898 (@1100-nm)

see elog #233906

(2) Fine z-filter scan, 2-nm bandpass, 2-nm steps, between 800-nm and 1030-nm, darks every 5-images.



First image is DECam_00394899 (@800-nm)
