International scientific conference Meeting on Operational and Research Capabilities for Better Understanding Solar-Terrestrial Interactions
Published by: Scientific Society Isaac Newton

In this study, ground -based solar observations conducted at Istanbul University Observatory and space -based data obtained from the SOHO (Solar and Heliospheric Observatory; Domingo et al. 1995) spacecraft were comparatively analyzed over a defined time int erval. The analysis utilized photospheric images and sunspot counts from both data sources. The ground -based observations from Istanbul University provide a valuable long -term dataset for monitoring solar activity, while SOHO's space -based observ ations offer high spatial and temporal resolution, enabling detailed tracking of short -term and dynamic solar phenomena. The study focused on the temporal distribution, morphology, and relative counts of sunspots from both datasets. Results indicate that g round and space -based observations complement each other effectively. The combined use of historical ground -based data and modern space telescope measurements offers significant advantages in solar activity studies. This integrated approach enhances unders tanding of solar magnetic field variations and contributes to improved modeling of solar -terrestrial interactions.
