Small-scale and global dynamos and the area and flux distributions of active regions, sunspot groups, and sunspots : a multi-database study [PDF]
, 2015 In this work, we take advantage of 11 different sunspot group, sunspot, and active region databases to characterize the area and flux distributions of photospheric magnetic structures.

Re-examining sunspot tilt angle to include anti-Hale statistics [PDF]
, 2014 Sunspot groups and bipolar magnetic regions (BMRs) serve as an observational diagnostic of the solar cycle. We use Debrecen Photohelographic Data (DPD) from 1974-2014 that determined sunspot tilt angles from daily white light observations, and data ...

Strong magnetic fields and unusual flows in sunspots
, 2022 This thesis presents a study of sunspots, which are the most prominent features observed on the solar surface. Their structure is governed by the magnetic field.

Submergence of magnetic flux in interaction of sunspot groups
, 2001 Submergence of magnetic flux is demonstrated in the process of evolution of sunspot groups NOAA 6850 (26 Sep.-07 Oct. 1991) and 7220/22 (06-17 July 1992). In both cases new magnetic flux emerges immediately behind an existing spotgroup. The new flux does

Sunspot areas and tilt angles for solar cycles 7-10
, 2015 Aims. Extending the knowledge about the properties of solar cycles into the past is essential for understanding the solar dynamo. This paper aims to estimate areas of sunspots observed by Schwabe in 1825−1867 and to calculate the tilt angles of sunspot ...

Food Science &Nutrition, Volume 14, Issue 6, June 2026.Cutaneous carotenoid measurements obtained non‐invasively by reflection spectroscopy (Veggie Meter and Biozoom) showed strong correlations with plasma carotenoid concentrations measured by HPLC in women across different BMI categories (Veggie Meter rs(151) = 0.697 and Biozoom rs(151) = 0.650, both p < 0.001).

Sunspot group tilt angle measurements from historical observations
, 2016 Sunspot positions from various historical sets of solar drawings are analyzed with respect to the tilt angles of bipolar sunspot groups. Data by Scheiner, Hevelius, Staudacher, Zucconi, Schwabe, and Sporer deliver a series of average tilt angles spanning

Space Weather, Volume 24, Issue 6, June 2026.Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

Joy’s Law, Anti-Hale classifications, and the evolution of emerging sunspot regions [PDF]
, 2016 This thesis aims to use analysis of the time dependence of sunspot locations and other physical characteristics to provide an improved empirical basis for understanding solar magnetic fields.
