Sodium Brightening of (3200) Phaethon Near Perihelion
Qicheng Zhang, Karl Battams, Quanzhi Ye +2
Sunskirting asteroid (3200) Phaethon has been repeatedly observed in STEREO HI1 imagery to anomalously brighten and produce an antisunward tail for a few days near each perihelion…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
Continued PSP/WISPR Observations of a Phaethon-related Dust Trail
Karl Battams, Angel J. Gutarra-Leon, Brendan M. Gallagher +7
We present an update to the first white-light detections of a dust trail observed closely following the orbit of asteroid (3200) Phaethon, as seen by the Wide-field Imager for Park…
A Machine-Learning-Ready Dataset Prepared from the Solar and Heliospheric Observatory Mission
Carl Shneider, Andong Hu, Ajay K. Tiwari +4
We present a Python tool to generate a standard dataset from solar images that allows for user-defined selection criteria and a range of pre-processing steps. Our Python tool works…
Collisional Evolution of the Inner Zodiacal Cloud
J. R. Szalay, P. Pokorny, D. M. Malaspina +9
The zodiacal cloud is one of the largest structures in the solar system and strongly governed by meteoroid collisions near the Sun. Collisional erosion occurs throughout the zodiac…
The LASCO Coronal Brightness Index
Karl Battams, Russell A. Howard, Hillary A. Dennison +2
We present the construction of a new white-light coronal brightness index (CBI) from the entire archive of observations recorded by the Large Angle Spectrometric Coronagraph (LASCO…
Parker Solar Probe Observations of a Dust Trail in the Orbit of (3200) Phaethon
Karl Battams, Matthew M. Knight, Michael S. P. Kelley +3
We present the identification and preliminary analysis of a dust trail following the orbit of (3200) Phaethon as seen in white light images recorded by the Wide-field Imager for Pa…
Oscillations of cometary tails: a vortex shedding phenomenon?
G. Nisticò, V. Vladimirov, V. M. Nakariakov +2
Context. During their journey to perihelion, comets may appear in the field-of-view of space-borne optical instruments, showing in some cases a nicely developed plasma tail extendi…
A Global Survey of EUV Corona Power Spectra
Karl Battams, Brendan M. Gallagher, Robert S. Weigel
We present results of a global survey of single-pixel intensity power spectra from a 12-hour time period on 26 June 2013 in a 1600x1600 pixel region from four channels of the Solar…
SOHO Comets: 20-Years and 3,000 Objects Later
Karl Battams, Matthew M. Knight
We present a summary of the more than 3,000 sungrazing and near-Sun comets discovered in coronagraph images returned by the Solar and Heliospheric Observatory (SOHO), since its lau…
Gone in a Blaze of Glory: the Demise of Comet C/2015 D1 (SOHO)
Man-To Hui, Quan-Zhi Ye, Matthew Knight +2
We present studies of C/2015 D1 (SOHO), the first sunskirting comet ever seen from ground stations over the past half century. The Solar and Heliospheric Observatory (SOHO) witness…
Dynamic Sublimation Pressure and the Catastrophic Breakup of Comet ISON
Jordan K. Steckloff, Brandon C. Johnson, Timothy Bowling +4
Previously proposed mechanisms have difficulty explaining the disruption of Comet C/2012 S1 (ISON) as it approached the Sun. We describe a novel cometary disruption mechanism where…
Stream Processing for Solar Physics: Applications and Implications for Big Solar Data
Karl Battams
Modern advances in space technology have enabled the capture and recording of unprecedented volumes of data. In the field of solar physics this is most readily apparent with the ad…
Preliminary Analysis of SOHO/STEREO Observations of Sungrazing Comet ISON (C/2012 S1) Around Perihelion
Matthew M. Knight, Karl Battams
We present photometric and morphological analysis of the behavior of sungrazing comet C/2012 S1 ISON in SOHO and STEREO images around its perihelion on 2013 November 28.779 UT. ISO…
