060_m22. (guides around the centre)???20:05Arc30SlowCCDs died. Not sure if this file existsIMPORTANT: Careful with reducing CCD4 data - CCD4 seems saturated. The series of Dome and Flat flats were taken to test both the data reduction and the effects of screen positioning on the uniformity of Dome flat illumination. Only some fo the offset sky frames were able to be reduced.

ADC died before these frames. We think this shouldn't affect the twilight flats but it might do. Possible high cirrus throughout
