STIX X-ray microflare observations during the Solar Orbiter commissioning phase
Andrea Francesco Battaglia, Jonas Saqri, Paolo Massa +34
The Spectrometer/Telescope for Imaging X-rays (STIX) is the HXR instrument onboard Solar Orbiter designed to observe solar flares over a broad range of flare sizes, between 4-150 k…
Sunspot characteristics at the onset of the Maunder Minimum based on the observations of Hevelius
V. M. S. Carrasco, J. M. Vaquero, M. C. Gallego +8
An analysis of the sunspot observations made by Hevelius during 1642-1645 is presented. These records are the only systematic sunspot observations just before the Maunder Minimum.…
Christian Horrebow's Sunspot Observations -- II. Construction of a Record of Sunspot Positions
Christoffer Karoff, Carsten Sønderskov Jørgensen, V. Senthamizh Pavai +1
The number of spots on the surface of the Sun is one of the best tracers of solar variability we have. The sunspot number is not only known to change in phase with the 11-year sola…
Sunspot positions, areas, and group tilt angles for 1611-1631 from observations by Christoph Scheiner
R. Arlt, V. Senthamizh Pavai, C. Schmiel +1
Digital images of the observations printed in the books "Rosa Ursina sive solis" and "Prodromus pro sole mobili" by Christoph Scheiner as well as the drawings from Scheiner's lette…
Sunspot group tilt angle measurements from historical observations
V. Senthamizh Pavai, R. Arlt, A. Diercke +2
Sunspot positions from various historical sets of solar drawings are analysed with respect to the tilt angles of bipolar sunspot groups. Data by Scheiner, Hevelius, Staudacher, Zuc…
Sunspot areas and tilt angles for solar cycles 7-10
V. Senthamizh Pavai, R. Arlt, M. Dasi-Espuig +2
Extending the knowledge about the properties of solar cycles into the past is essential for understanding the solar dynamo. This paper aims at estimating areas of sunspots observed…
