TL;DR: In this article, the authors examine repetitive substorms, identified using particle injections and positive H bays on the night side, that occur during corotating high-speed streams associated with coronal holes.

TL;DR: In this article, the authors examined the relationship among coronal holes (CHs), corotating interaction regions (CIRs), and geomagnetic storms in the period 1996-2003.

TL;DR: In this article, the authors examined the geoeffectiveness of coronal mass ejection (CME) based on the field orientation (N or S) in a CME source region and its dependence on interplanetary CME (ICME) classification.

TL;DR: The Balloon-borne Investigation of Temperature and Speed of Electrons in the corona (BITSE) mission as mentioned in this paper used a single-stage coronagraph and a Wallops Arc Second Pointer (WASP) for Sun pointing.

TL;DR: The Balloonborne Investigation of Temperature and Speed of Electrons in the corona (BITSE) mission as discussed by the authors used an externally occulted single stage coronagraph developed at NASA's Goddard Space Flight Center in collaboration with the Korea Astronomy and Space Science Institute (KASI).
