Interplanetary magnetic field B(y) control of dayside auroras

Viking UV images for large positive and negative interplanetary magnetic field (IMF) are studied to ascertain IMF B(y) component effects on the dayside auroral oval in March-November 1986. It is found that the intensity of dayside auroras tends to increase for negative IMF B(y) and to increase for p...

Description
Summary:Viking UV images for large positive and negative interplanetary magnetic field (IMF) are studied to ascertain IMF B(y) component effects on the dayside auroral oval in March-November 1986. It is found that the intensity of dayside auroras tends to increase for negative IMF B(y) and to increase for positive B(y), so that the negative conditions appear preferable for observations of the dayside auroras.
