TL;DR: Several groups of impulsive flare accelerated nonrelativistic solar electron events occurred in November and December 1990 as discussed by the authors, and these departures are associated with a structure in the interplanetary magnetic field having a width of about 4 x 10 exp 6 km at 1.37 AU.

TL;DR: The Ramaty High Energy Solar Spectroscopic Imager (RHESSI) as mentioned in this paper is capable of measuring the polarization of hard X-rays (20-100 keV) from solar flares.

TL;DR: In this paper, the positions of sharp boundaries delineating transitions from one flow state to another were determined by two instruments of the RPA-Copernic experiment aboard Giotto during its encounter with Comet Halley.

TL;DR: In this paper, a mission concept that uses 3-unit cubesats to perform new measurements of lunar magnetic fields, less than 100 meters above the Moon's surface, was developed, which called for sending the cubesats on impact trajectories to strongly magnetic regions on the surface, and transmitting measurements in real-time to a nearby spacecraft, or directly to the Earth, up until milliseconds before impact.

TL;DR: In this paper, the first observations of ≃2 MeV ion bursts in the upstream region and the magnetosheath of the WIND spacecraft were presented, which has strong implications for the ion source and acceleration mechanisms.
