Abstract
Geomagnetic pulsations of the Pc4–5 type at the Barentsburg Observatory for December 2007 to January 2008 are compared with the auroral intensity variations based on the photometric records at the same observatory. In all cases, auroral pulsations similar in shape are also observed simultaneously with geomagnetic pulsations. In the morning and daytime hours, the pulsation radiance maxima fall on the positive half-periods in the H component at the observation point; in the evening and nighttime hours, they fall on the negative half-periods.
