We report here the presence of previously unobserved NII emissions in several spectra of aurora from the dayside cusp region taken near Longyearbyen, Spitzbergen (74.3¿N geomagnetic). The presence of the 3d3P¿-4p3S transition giving rise to the triplet (6809, 6834, 6847 ¿) is particularly obvious, but the spectra also show strong evidence of other NII emissions such as those from the 3d3D¿-4p3D level. The forbidden [NII> (6548, 6584 ¿) doublet seems also to be present, but less obvious than the NII (6809, 6834, 6847 ¿) triplet. The presence or the enhanced level of these permitted emissions seems, on two occasions, to coincide with a sudden decrease in the characteristic energy of the local particle precipitation and with a high latitude substorm on the nightside. Integration time is so large (30 min) as to preclude a more extact correlation with the substorm. However, two otherwise identical situations occurred with no nightside substorm and neither increased NII emissions nor decreased particle energies were observed on the dayside.
