The operator told me I should not notice any effects of the power dip and I did not except for one brief commment from CIMA. CIMA gave the orange warning "Observing when not on source" at the point in the scan when the power dip occured and then returned to normal. The data appear fine at first glance and the file is of the right size. For some reason during file 0013 CIMA did not give the orange warning "Observing when not on source" as it did for every other drift. Update 06Apr21 (martha) We learned today that one of ALFA's refrigerators failed around 1900 AST. See the note on Phil's web page: http://www.naic.edu/~phil/mbeam/refrigfail_apr06.html The 20K stage dewar temperature warmed up to about 50K (by 1am 19apr06). The a2010 data show a Tsys increase of 2-3 K.
