The MSX, POLAR, and FAST satellites observed several bright auroral arcs over Scandinavia and Russia from 19:27 to 19:49 UT on 9 February 1997 with Kp 5+. The POLAR satellite was near apogee and recorded the entire Northern Hemisphere at ultraviolet, visible, and X-ray wavelengths. The FAST satellite recorded electron and ion particle spectra and flux density at high time resolution as it passed near Novaya Zemlya. The MSX satellite observed high spatial and temporal resolution images and spectral data with a suite of co-aligned instruments measuring wavelengths from the UV to far IR. The Loparskaya ground site in Russia measured bright arcs in the 630.0 nm OI transition with an all-sky camera coincident with the MSX observation and was useful in defining the region of particle dosing along the MSX line of sight. The POLAR images provide wide spatial coverage over the region of interest, while MSX, FAST, and the Loparskaya ground site provide nearly simultaneous information on several arcs from 19:27-19:30 UT. The MSX instruments were observing tangent heights in the range from 70 to 130 km in the vicinity of the same magnetic field lines along which FAST was making exoatmospheric particle measurements at an altitude of 3800 km. Auroral optical and infrared emissions observed by the MSX satellite will be compared with the optical data from the ground site and the particle data from FAST. MSX Spectral Imager (SPIM) data will be used to estimate the ion-pair production rate along the MSX line of sight based on N2+ emissions at 4278 A. The MSX MWIR auroral enhancement has been compared with the AARC (Auroral Atmospheric Radiance Code) model and for these dosing and viewing conditions as documented by the multi-platform sensors. The well characterized auroral conditions are self consistent and analysis indicates the MWIR auroral enhancement in this instance is due primarily to vibrationally excited NO+.
