70 years of Sunspot Observations at Kanzelhöhe Observatory: systematic study of parameters affecting the derivation of the relative sunspot number
Werner Pötzi, Astrid M. Veronig, Manuela Temmer +3
Kanzelhöhe Observatory (KSO) was founded during World War II by the "Deutsche Luftwaffe" (German Airforces) as one station of a network of observatories, which should provide infor…
Thermosphere and geomagnetic response to interplanetary coronal mass ejections observed by ACE and GRACE: Statistical results
S. Krauss, M. Temmer, A. M. Veronig +2
For the period July 2003 to August 2010, the interplanetary coronal mass ejection (ICME) catalogue maintained by Richardson and Cane lists 106 Earth-directed events, which have bee…
IAU commission 10 "Solar Activity": Legacy report and triennial report for 2012-2015
Carolus J. Schrijver, Lyndsay Fletcher, Lidia van Driel-Gesztelyi +8
After more than half a century of community support related to the science of "solar activity'', IAU's Commission 10 was formally discontinued in 2015, to be succeeded by C.E2 with…
Coronal response to an EUV wave from DEM analysis
K. Vanninathan, A. M. Veronig, K. Dissauer +3
EUV (Extreme-Ultraviolet) waves are globally propagating disturbances that have been observed since the era of the SoHO/EIT instrument. Although the kinematics of the wave front an…
Improvements on coronal hole detection in SDO/AIA images using supervised classification
Martin A. Reiss, Stefan J. Hofmeister, Ruben De Visscher +5
We demonstrate the use of machine learning algorithms in combination with segmentation techniques in order to distinguish coronal holes and filaments in SDO/AIA EUV images of the S…
Two-dimensional segmentation of small convective patterns in radiation hydrodynamics simulations
B. Lemmerer, D. Utz, A. Hanslmeier +4
Recent results from high-resolution solar granulation observations indicate the existence of a population of small granular cells that are smaller than 600 km in diameter. These sm…
