Effect of Additional Magnetograph Observations From Different Lagrangian Points in Sun‐Earth System on Predicted Properties of Quasi‐Steady Solar Wind at 1 AU

Space Weather, 2020
Modeling the space weather conditions for a near‐Earth environment depends on a proper representation of magnetic fields on the Sun. There are discussions in the community with respect to the value of observations taken at several Lagrangian points (L1 ...

Latitude Quenching Nonlinearity in the Solar Dynamo

Astrophysical Journal
We compare two candidate nonlinearities for regulating the solar cycle within the Babcock–Leighton paradigm: tilt quenching (whereby the tilt of active regions is reduced in stronger cycles) and latitude quenching (whereby flux emerges at higher ...

Effectiveness of Search for Unrelated Donor of Hematopoietic Stem Cells using Russian System Bone Marrow Donor Search: Experience of RM Gorbacheva Scientific Research Institute of Pediatric Hematology and Transplantation

Klinicheskaya Onkogematologiya/Clinical Oncohematology, 2017
Background & Aims. The key condition for allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the presence of HLA-compatible related or unrelated donor.

Forward Modeling of Coronal Mass Ejection Flux Ropes in the Inner Heliosphere with 3DCORE. [PDF]

Space Weather, 2018
Abstract Forecasting the geomagnetic effects of solar storms, known as coronal mass ejections (CMEs), is currently severely limited by our inability to predict the magnetic field configuration in the CME magnetic core and by observational effects of a single spacecraft trajectory through its 3‐D structure. CME magnetic flux ropes can lead to continuous

The Dependence of the Peak Velocity of High-Speed Solar Wind Streams as Measured in the Ecliptic by ACE and the STEREO satellites on the Area and Co-latitude of Their Solar Source Coronal Holes. [PDF]

J Geophys Res Space Phys, 2018
Abstract We study the properties of 115 coronal holes in the time range from August 2010 to March 2017, the peak velocities of the corresponding high‐speed streams as measured in the ecliptic at 1 AU, and the corresponding changes of the Kp index as marker of their geoeffectiveness. We find that the peak velocities of high‐speed streams depend strongly

Sunspot observations at Kawaguchi Science Museum: 1972 – 2013

Geoscience Data Journal, Volume 10, Issue 1, Page 87-98, January 2023., 2023
This article visualises a database for Hitoshi Takuma's sunspot observations and background metadata. Abstract Individual sunspot observations have formed a ground basis of international sunspot number, a unique reference for long‐term solar variability in the centennial timescale. The original datasets were subjected to exploitations and analyses upon

Characterization of chromospheric activity based on Sun‐as‐a‐star spectral and disk‐resolved activity indices

Astronomische Nachrichten, Volume 343, Issue 5, June 2022., 2022
Abstract The strong chromospheric absorption lines Ca ii H & K are tightly connected to stellar surface magnetic fields. Only for the Sun, spectral activity indices can be related to evolving magnetic features on the solar disk. The Solar Disk‐Integrated (SDI) telescope feeds the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) of the ...
