A stable auroral red (SAR) arc was recorded the night of September 28/29 from stations at Fritz Peak, Colorado, and Richland, Washington. The first direct determination of position and altitude of an SAR arc was accomplished by triangulation from these two stations. The appearance of this arc marks the definite recurrence of this phenomenon after an apparent absence of four years. The arc occurred southward of an intense auroral display, and it was aligned parallel to lines of constant L. Average intensity of [O I] 6300 A emission in the brightest part of the arc was approximately 150 R. Altitude of the brightest region was determined from angular coordinates at the two stations to be 400 km at 0745 UT. A typical width across the narrow dimension of the arc was 160 km between half-maximum intensity values. A sector of the arc almost 4200 km long was simultaneously within the combined range of the two stations. The arc occurred during a period of high magnetic activity, and though a comparably intense aurora borealis occurred the night before (September 27/28), no SAR arc was observed from either station.
