Visibility, solar radiation, halos, coronas, and the 
blueness of the sky were not included in the observation- 
al work of the Carnegie. The optical observations were 
made incidentally and reported only briefly in the log ab- 
stract. 
The aurora borealis was observed on three nights 
during the cruise, namely, on August 3, 4, and 6, 1928, 
between latitudes 48° and 58° north in the North Atlantic.
