TL;DR
This paper presents a comprehensive catalog of solar observations from Hvar Observatory between 2010 and 2019, characterizing active regions, filaments, and flares, and analyzing their properties and biases.
Contribution
It provides the first detailed catalog of Hvar Observatory solar observations, including classifications and analysis of observed phenomena, with publicly available data for further research.
Findings
HVAR observations are biased towards complex active regions and stronger flares.
The catalog shows a tendency to observe partial eruptions and longer-lasting phenomena.
Remote and in situ data show good agreement in flare-CME-ICME associations.
Abstract
We compile the catalog of Hvar Observatory solar observations in the time period corresponding to regular digitally stored chromospheric and photospheric observations 2010-2019. We make basic characterisation of observed phenomena and compare them to catalogs which are based on full disc solar images. We compile a catalog of observed ARs consisting of 1100 entries, where each AR is classified according to McIntosh and Mt Wilson classifications. We find that HVAR observations are biased towards more frequently observing more complex ARs and observing them in longer time periods, likely related to the small FOV not encompassing the whole solar disc. In H observations we catalog conspicuous filaments/prominences and flares. We characterise filaments according to their location, chirality (if possible) and eruptive signatures. Analysis of the eruptive filaments reveals a slight bias…
