First polar and 1995-034 observations of the midaltitude cusp during a persistent northward IMF condition. Geophysical Research Letters 24: doi: 10.1029/97GL01291. issn: 0094-8276.

We present the first observations by Polar and 1995-034 of the mid-altitude cusp. On May 29, 1996, the Polar and 1995-034 spacecraft crossed into an extended cusp region. The region was characterized by intense fluxes of solar wind like ions in the energy range 1--10 keV that had angular distributions that showed evidence of flows and trapping. The ion composition data are combined with energetic proton observations from Polar and plasma observations from 1995-034 and DMSP satellites to examine the spatial and temporal extent and plasma characteristics of the cusp during a persistent northward IMF condition. The composition data is consistent with expected solar wind composition with a source temperature of ~1.25¿106 K. The combined spacecraft observations show an extended cusp-like region, probably produced by northward IMF.¿ 1997 American Geophysical Union
