“…The TRICE‐2 sounding rocket mission was launched from the Andoya Space Flight Center in Norway on 8 December 2018. Figure 1, generated with the AGI STK software, shows an overview plot of the TRICE‐2 rocket trajectories through the northern cusp, with the yellow transparent box visualizing an average location for the cusp to guide the eye (e.g., Petrinec et al., 2023). The actual cusp encounters of the High‐Flyer and Low‐Flyer rockets are marked with red segments along their respective trajectories, based on the observation of precipitating solar wind ions along the trajectories of the rockets.…”

Two sounding rockets, designated TRICE‐2, were launched on 8 December 2018 into the northern cusp region. The two rockets were designated the high‐ and low‐flyers, respectively, and launched 2 min apart to investigate cusp structures, specifically their spatial or temporal nature. 2 hr prior to the cusp encounter by the TRICE‐2 rockets, the MMS satellites, located in the magnetopause boundary layer, observed switching ion beams under very similar IMF conditions as later observed by TRICE‐2. The observed ion beam switch in the boundary layer defined the location of the primary dayside X‐line. Both, TRICE‐2 and MMS, also observed the signatures of multiple X‐lines at the magnetopause, overlapping ion‐energy dispersions in the cusp and counterstreaming ion beams in the magnetopause boundary layer, respectively. In addition to the TRICE‐2 cusp observations, ionospheric convection patterns from the SuperDARN radar are used to explain the vastly different cusp ion signatures observed by the TRICE‐2 rockets. While the high‐flyer rocket progressed north through the center of the cusp, the low‐flyer rocket drifted off to the east and crossed into the dusk convection cell, traveling perpendicular to the ionospheric convection direction before reaching the poleward oriented section of the convection cell also observed by the high‐flyer counterpart.

“…We identify two features which should be considered in the subsequent statistical report: (a) the coverage in the magnetic local time is not symmetric across noon, and the regions closer to dusk are more sampled than those close to dawn, and (b) the magnetic latitudes under 60°are similarly sampled closer to dusk. According to the cusp location model of Petrinec et al (2023), compiled from published studies and applied to the recent TRICE-2 campaign of cusp region observations during southward IMF, the cusp is (a) centered at 12.6 h when B y = 0, (b) moves duskward with increasing A red dot is drawn at each of the identified peaks using our method.…”

“…We must also consider whether the orbit of the satellite has an impact on the observed preference for positive B y . The structure of the time spent at each magnetic coordinate, shown in Figure 4, combined with the cusp location model of Petrinec et al (2023), indicates the satellite over the sample cusp locations for a positive B y . We are, therefore, unable to definitely conclude whether this bias contributes to exaggerating the preference for B y , or whether this bias generates a false appearance of a preference altogether.…”

This article presents a statistical analysis of overlapping double ion-energy dispersion events in the northern cusp (“double dispersion”). Double dispersion in either cusp is a phenomenon associated with multiple reconnections occurring on the dayside magnetosphere as a result of its constant interaction with the variable solar wind. Using observations from a low Earth orbiting (LEO) Defense Meteorological Satellite Program (DMSP) satellite, we analyze 138 dayside events selected by the automatic algorithm extended from our previous work. We conducted a correlation study between the number of detected double dispersion events and 1) the month of the year to analyze the seasonal response of the cusp, and 2) solar wind interplanetary magnetic field (IMF) components and clock/cone angles to investigate its relationship with magnetic reconnection. We found that dispersion events occur more frequently during the northern summer months (i.e., when the dipole is tilted Sunward) and when the By component of IMF is positive. In addition, we provide a machine-readable list of the events and the code used to automatically detect the events.
