The Calorimetric Electron Telescope (CALET), in operation on the International Space Station since 2015, collected a large sample of cosmic-ray iron over a wide energy interval. In…
New cosmic ray observations at Syowa Station in the Antarctic for space weather study
C. Kato, W. Kihara, Y. Ko +9
Muon detectors and neutron monitors were recently installed at Syowa Station, in the Antarctic, to observe different types of secondary particles resulting from cosmic ray interact…
A Peculiar ICME Event in August 2018 Observed with the Global Muon Detector Network
W. Kihara, K. Munakata, C. Kato +20
We demonstrate that global observations of high-energy cosmic rays contribute to understanding unique characteristics of a large-scale magnetic flux rope causing a magnetic storm i…
Direct Measurement of the Cosmic-Ray Carbon and Oxygen Spectra from 10 GeV to 2.2 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +81
In this paper, we present the measurement of the energy spectra of carbon and oxygen in cosmic rays based on observations with the Calorimetric Electron Telescope (CALET) on the In…
MAXI/SSC All-sky maps from 0.7 keV to 4 keV
Satoshi Nakahira, Hiroshi Tsunemi, Hiroshi Tomida +3
By accumulating data from the Solid-state Slit Camera (SSC) on board the MAXI mission for 2 years from 2009 to 2011, diffuse X-ray background maps were obtained in energies of 0.7-…
Extended Measurement of the Cosmic-Ray Electron and Positron Spectrum from 11 GeV to 4.8 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +88
Extended results on the cosmic-ray electron + positron spectrum from 11 GeV to 4.8 TeV are presented based on observations with the Calorimetric Electron Telescope (CALET) on the I…
On-orbit Operations and Offline Data Processing of CALET onboard the ISS
Y. Asaoka, S. Ozawa, S. Torii +89
The CALorimetric Electron Telescope (CALET), launched for installation on the International Space Station (ISS) in August, 2015, has been accumulating scientific data since October…
Energy Calibration of CALET Onboard the International Space Station
Y. Asaoka, Y. Akaike, Y. Komiya +91
In August 2015, the CALorimetric Electron Telescope (CALET), designed for long exposure observations of high energy cosmic rays, docked with the International Space Station (ISS) a…
Energy Spectrum of Cosmic-ray Electron and Positron from 10 GeV to 3 TeV Observed with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +88
First results of a cosmic-ray electron + positron spectrum, from 10 GeV to 3 TeV, is presented based upon observations with the CALET instrument on the ISS starting in October, 201…
The earliest drawings of datable auroras and a two-tail comet from the Syriac Chronicle of Zūqnīn
Hisashi Hayakawa, Yasuyuki Mitsuma, Yasunori Fujiwara +7
People have probably been watching the sky since the beginning of human history. Observers in pre-telescopic ages recorded anomalous events and these astronomical records in the hi…
East Asian Observations of Low Latitude Aurora during the Carrington Magnetic Storm
Hisashi Hayakawa, Kiyomi Iwahashi, Harufumi Tamazawa +6
The magnetic storm around 1859 September 2, caused by so-called Carrington flare, was the most intense in the history of modern scientific observations, and hence is considered to…
Ionization of protoplanetary disks by galactic cosmic rays, solar protons, and by supernova remnants
Ryuho Kataoka, Tatsuhiko Sato
Galactic cosmic rays and solar protons ionize the present terrestrial atmosphere, and the air showers are simulated by well-tested Monte-Carlo simulations, such as PHITS code. We u…
"Unusual Rainbow and White Rainbow" A new auroral candidate in oriental historical sources
Hisashi Hayakawa, Hiroaki Isobe, Akito Davis Kawamura +3
Solar activity has been recorded as auroras or sunspots in various historical sources. These records are of much importance for investigating both long-term solar activities and ex…
Interplanetary particle transport simulation for warning system for aviation exposure to solar energetic particles
Yûki Kubo, Ryuho Kataoka, Tatsuhiko Sato
Solar energetic particles (SEPs) are one of the extreme space weather phenomena. A huge SEP event increases the radiation dose received by aircrews, who should be warned of such ev…
