An analysis of the solar differential rotation in solar cycle No. 19 (1954-1964) determined using Kanzelhoehe sunspot group positions
Ivana Poljancic Beljan, Luka Sibenik, Tomislav Jurkic +7
We study solar differential rotation (DR) for solar cycle No. 19 (1954-1964) by tracing sunspot groups on the sunspot drawings of Kanzelhoehe Observatory for Solar and Environmenta…
Meridional Motions and Reynolds Stress Determined by Using Kanzelhöhe Drawings and White Light Solar Images from 1964 to 2016
Domagoj Ruždjak, Davor Sudar, Roman Brajša +6
Sunspot position data obtained from Kanzelhöhe Observatory for Solar and Environmental Research (KSO) sunspot drawings and white light images in the period 1964 to 2016 were used t…
A Relationship between the Solar Rotation and Activity Analysed by Tracing Sunspot Groups
Domagoj Ruždjak, Roman Brajša, Davor Sudar +2
The sunspot position from Greenwich Photoheliographic Results (GPR), US Air Force Solar Optical Observing Network and National Oceanic and Atmospheric Administration (USAF/NOAA), a…
Meridional Motion and Reynolds Stress from Debrecen Photoheliographic Data
Davor Sudar, Roman Brajša, Ivica Skokić +2
The Debrecen Photoheliographic Data catalogue is a continuation of the Greenwich Photoheliographic Results providing daily positions of sunspots and sunspot groups. We analyse the…
