Titolo: | The potential of Ca II K observations for solar activity and variability studies | Autori: | ERMOLLI, Ilaria CHATZISTERGOS, THEODOSIOS Krivova, Natalie A. Solanki, Sami K. |
Data pubblicazione: | 2018 | Titolo del volume in cui è pubblicato il poster: | Long-term Datasets for the Understanding of Solar and Stellar Magnetic Cycles | Serie: | PROCEEDINGS OF THE INTERNATIONAL ASTRONOMICAL UNION | Numero: | vol. 13, S340 | Da pagina:: | 115 | Abstract: | Several observatories around the globe started regular full-disc imaging of the solar atmosphere in the Ca II K line in the early decades of the 20<SUP>th</SUP> century. These observations are continued today at a few sites with either old spectroheliographs or modern telescopes equipped with narrow-band filters. The Ca II K time series are unique in representing long-term variations of the Sun's chromospheric magnetic field. However, meaningful results from their analysis require accurate processing of the available data and robust merging of the information stored in different archives. This paper provides an overview of the historical and modern full-disc Ca II K observations, with focus on their quality and the main results obtained from their analysis over the last decade. | Titolo del convegno: | Long-term Datasets for the Understanding of Solar and Stellar Magnetic Cycles | Luogo del convegno: | Jaipur, India | Periodo del convegno: | 19- 23 February, 2018 | URI: | http://hdl.handle.net/20.500.12386/34224 | URL: | https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/potential-of-ca-ii-k-observations-for-solar-activity-and-variability-studies/66A7C3F4801AB6E00AB9D56A78CA7005 http://arxiv.org/abs/1805.04483v1 |
