[Comment on “Record aurora over North America,” and “Effects of the March 1989 solar activity” by Joe Allen, et al.] southern aurora



The spectacular equatorward extent of auroral displays over North America, along with disruptions of radio communications and a power blackout, on the occasion of the March 1989 solar and geomagnetic disturbances, as reported in Eos (May 16, p. 595; November 14, p. 1479), calls for supplementary information from the southern hemisphere. Immediately after receiving some spontaneous descriptions by private observers in central Patagonia, we started a nationwide enquiry in search of similar data from continental and naval weather stations, as well as from radio and astronomy amateurs.
