Reconstructing solar magnetic fields from historical observations X. Effect of magnetic field inclination and boundary structure on AIA 1600 Å emission
Ismo Tähtinen, Alexei A. Pevtsov, Timo Asikainen +1
The relation between the intensity of chromospheric emissions and the photospheric magnetic field strength has been examined in several studies, but the effect of the magnetic fiel…
Transition to a weaker Sun: Changes in the solar atmosphere during the decay of the Modern Maximum
K. Mursula, A. A. Pevtsov, T. Asikainen +2
The Sun experienced a period of unprecedented activity during the 20th century, now called the Modern Maximum (MM). The decay of the MM after cycle 19 has changed the Sun, the heli…
A Universal Method for Solar Filament Detection from H-alpha Observations using Semi-supervised Deep Learning
Andrea Diercke, Robert Jarolim, Christoph Kuckein +7
Filaments are omnipresent features in the solar atmosphere. Their location, properties and time evolution can provide information about changes in solar activity and assist the ope…
Ground-based monitoring of the variability of visible Solar spectral lines for improved understanding of solar and stellar magnetism and dynamics
S. Criscuoli, L. Bertello, D. P. Choudhary +7
Long-term high-cadence measurements of stellar spectral variability are fundamental to better understand stellar atmospheric properties and stellar magnetism. These, in turn, are f…
Ground-based Solar Observations for Space Weather Forecasting
A. G. Tlatov, A. A. Pevtsov
The possibilities of organizing an observation service for solar activity in order to provide space weather forecasting are considered. The most promising at this stage is the crea…
Camera update for GONG refurbishment: Development and validation
Anna L. H. Hughes, Timothy J. Purdy, Thomas M. Wentzel +9
This report provides a brief summary of the properties of new cameras selected for NSF's Global Oscillations Network Group (GONG) facilities operated by the NSO Integrated Synoptic…
