Abstract We present a photometric detection of the first brightness dips unique variable star KIC 8462852 since end Kepler space mission in 2013 May. Our regular surveillance started 2015 October, and sequence dipping began 2017 May continuing on through 2017, when was no longer visible from Earth. distinguish four main 1%–2.5% dips, named “ Elsie ,” Celeste Skara Brae Angkor which persist timescales several days to weeks. results so far are as follows: (i) there apparent changes stellar...
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...
Abstract. Accurate high-precision magnetic field measurements are a significant challenge for many applications, including constellation missions studying space plasmas. Instrument stability and orthogonality essential to enable meaningful comparison between disparate satellites in without extensive cross-calibration efforts. Here we describe the design characterization of Tesseract – fluxgate magnetometer sensor designed low-noise, high-stability applications. Tesseract's takes advantage...
Abstract. Ongoing innovation in next generation fluxgate magnetometry is important for enabling future investigations of space plasma, especially multi-spacecraft experimental studies energy transport the magnetosphere and solar wind. Demonstrating spaceflight capability novel designs an step instrument development process; however, large-scale satellite missions are often unwilling to accept risks without flight heritage. The Tesseract – a magnetometer sensor design-had opportunity...

Abstract. Fluxgate magnetometers provide sensitive and stable measurements of the static low-frequency vector magnetic field. Fluxgates form a field measurement by periodically saturating ferromagnetic core intrinsic noise this material can determine floor instrument. We present results an empirical experiment to understand physical parameters that influence fluxgate cores. compare two permalloy alloys – historical standard 6 % molybdenum alloy new 28 copper alloy. examine geometry using 1...
Abstract Fluxgate magnetometers are an important tool for measuring space plasmas. In situ magnetic field investigations often involve small perturbations of a large background field, so robust instrument calibration is critical to accurately resolving geophysical signals. instruments aboard recent science missions have observed anomalies that been attributed thermal gradients across the sensor. Here we present data from laboratory experimental investigation effects on fluxgate and...
