Shock Connectivity and the Late Cycle 24 Solar Energetic Particle Events in July and September 2017

Corresponding author: Janet Luhmann ([email protected]) Key Points: Observer shock connectivity explains the SEP observations during the July and September 2017 events. The July and September 2017 solar and SEP events had similar characteristics due to similar source region and eruptions. The July and September 2017 events seemed to arise in conjunction with the appearance of a pseudostreamer, a possible alternate ICME source.

Abstract As solar activity steadily declined toward the cycle 24 minimum in the early months of 2017, the expectation for major Solar Energetic Particle (SEP) events diminished with the sunspot number. It was thus surprising (though not unprecedented) when a new, potentially significant active region rotated around the East limb in early July that by mid-month was producing a series of coronal eruptions, reaching a crescendo around July 23. This series, apparently associated with the birth of a growing pseudostreamer, produced the largest SEP event(s) seen since the solar maximum years. -
The Van Allen Probes' Contribution to the Space Weather System
L. J. Zanetti et al. The Van Allen Probes’ Contribution to the Space Weather System Lawrence J. Zanetti, Ramona L. Kessel, Barry H. Mauk, Aleksandr Y. Ukhorskiy, Nicola J. Fox, Robin J. Barnes, Michele Weiss, Thomas S. Sotirelis, and NourEddine Raouafi ABSTRACT The Van Allen Probes mission, formerly the Radiation Belt Storm Probes mission, was renamed soon after launch to honor the late James Van Allen, who discovered Earth’s radiation belts at the beginning of the space age. While most of the science data are telemetered to the ground using a store-and-then-dump schedule, some of the space weather data are broadcast continu- ously when the Probes are not sending down the science data (approximately 90% of the time). This space weather data set is captured by contributed ground stations around the world (pres- ently Korea Astronomy and Space Science Institute and the Institute of Atmospheric Physics, Czech Republic), automatically sent to the ground facility at the Johns Hopkins University Applied Phys- ics Laboratory, converted to scientific units, and published online in the form of digital data and plots—all within less than 15 minutes from the time that the data are accumulated onboard the Probes. The real-time Van Allen Probes space weather information is publicly accessible via the Van Allen Probes Gateway web interface. INTRODUCTION The overarching goal of the study of space weather ing radiation, were the impetus for implementing a space is to understand and address the issues caused by solar weather broadcast capability on NASA’s Van Allen disturbances and the effects of those issues on humans Probes’ twin pair of satellites, which were launched in and technological systems. -

In ad- dition to instruments devoted to taking measurements of the local solar wind, the spacecraft carries a visible imager: the Wide-field Imager for Solar PRobe (WISPR). WISPR will take advantage of the proximity of the spacecraft to the Sun to perform local imaging of the near-Sun environment. WISPR will observe coronal structures at high spatial and time resolutions, although the observed plane-of-sky will rapidly change because of the fast transit at the perihelia. We present a concise description of the PSP mission, with particular regard to the WISPR instrument, discussing its main scientific goals, targets of observations, and outlining the possible synergies with current and upcoming space missions. 1. – The Parker Solar Probe mission Parker Solar Probe (PSP) is a historic NASA mission aiming to explore for the first time the near-Sun environment [1] (1). PSP was launched on 12 August 2018 on a Delta IV Heavy rocket from Cape Canaveral Air Force Station for a seven-year-long mission. -

Solar Probe Plus (SPP)
Pre-decisional – For NASA Internal Use Only Solar Probe Plus (SPP) Committee on Solar and Space Physics 5 October 2016 Joe Smith Program Executive NASA Headquarters 5 October 2016 1 Solar Probe Plus (SPP) Overview Using in-situ measurements made closer to the Sun than by any previous spacecraft, SPP will determine the mechanisms that produce the fast and slow solar winds, coronal heating, and the transport of energetic particles. Solar Probe Plus will fly to less than 10 solar radii (Rs) of the Sun, having “walked in” from 35 Rs over 24 orbits.

The concept for a “Solar Probe” dates back to “Simpson’s Committee” of the Space Science Board (National Academy of Sciences, 24 October 1958) ‒ The need for extraordinary knowledge of Sun from remote observations, theory, and modeling to answer the questions: – Why is the solar corona so much hotter than the photosphere? – How is the solar wind accelerated? . -
