The conjugacy of bay‐type magnetic variations at midlatitude was investigated using data from the Cold Bay, Alaska, and Oamaru, New Zealand, pair (L= 2.6). Of twenty‐four intervals representing positive bay activity which were examined, the majority showed substantial agreement. Eleven intervals could be considered anomalous in all or some features. At midlatitude positive bays seem to result from the return current part of auroral zone electrojets. Intervals showing noncorrelation indicate departures of the primary electrojet from a conjugate pattern. Short period magnetic pulsations were also observed as a conjugate phenomenon. They could not be studied in detail owing to the insensitivity of the magnetomet
