Abstract The ACES‐II Low sounding rocket, which launched from Andøya Space Center in Andenes, Norway, on 20 November 2022, made low altitude observations consistent with characteristics of the Ionosphere Feedback Instability (IFI) as it traversed a quiet, discrete auroral arc. Small scale Alfvénic signatures are observed regions depleted ionospheric plasma density, large perpendicular electric fields, and matched Pedersen Alfvén conductivities—all observational preconditions required for...
We investigate the nature of small-scale irregularities observed in cusp by Twin Rockets to Investigate Cusp Electrodynamics-2 (TRICE-2) regions enhanced phase scintillations and high-frequency coherent radar backscatter. take advantage fact that were detected spatially separated probes, present an interferometric analysis both electron density electric field fluctuations. provide evidence fluctuations spanning a few decameters about meter have low velocity plasma reference frame are...
The plasma in the cusp ionosphere is subject to particle precipitation, which important for development of large-scale irregularities density. These can be broken down into smaller scales have been linked strong scintillations Global Navigation Satellite System (GNSS) signals. We present power spectra density regions with and without auroral precipitation based on in-situ measurements from Twin Rockets Investigate Cusp Electrodynamics-2 (TRICE-2) mission, consisting two sounding rockets...
Abstract On December 08, 2018 the Twin Rocket Investigation of Cusp Electrodynamics 2 (TRICE 2) mission was successfully launched. The consisted two sounding rockets, each carrying a payload capable measuring electron and ion distributions, electric magnetic fields, plasma waves occurring in northern magnetospheric cusp. This study highlights wave observations obtained by TRICE cusp from multiscale (MMS) spacecraft at low‐latitude magnetopause hours prior to traversal Within cusp, typical...
Abstract During the Twin Rockets to Investigate Cusp Electrodynamics (TRICE‐2) High‐Flyer rocket's passage through cusp high frequency (HF) radio wave receiver observed three intervals of banded upper‐hybrid (UH) waves. The bands begin at UH ( 1.2–1.3 MHz), descending as low 1.1 MHz, with amplitudes hundreds mV/m. spacing are 4.5–6 kHz and number ranges from 3 10. Simultaneously, very (VLF) lower‐hybrid (LH) waves ranging 1 10 mV/m frequencies kHz. Slight variations spacings in were closely...
We present a comparative analysis of urban magnetic fields between two American cities: Berkeley (California) and Brooklyn Borough New York City (New York). Our uses data taken over four-week period during which field were continuously recorded using fluxgate magnetometer with 70 pT/Hz noise. identified significant differences in the signatures. In particular, we noticed that reaches near-zero activity at night, whereas continues nighttime. also auxiliary measurements acquired...
