Catalog of Long-term Transient Sources in the First 10 yr of Fermi-LAT Data
We present the first Fermi Large Area Telescope (LAT) catalog of long-term γ-ray transient sources (1FLT). This comprises sources that were detected on monthly...
Chromospheric Dynamics of an Umbral Flare Kernel-Based on Coordinated SUNRISE III SCIP and Domeless Solar Telescope Observations
We report imaging spectroscopic observations of an M1.4 solar flare obtained during a coordinated observation between the infrared spectropolarimeter SCIP...
Circular polarization of the CA II H and K lines in solar quiet and active regions
A representative set of profiles is presented for the Ca II H resonace line in Stokes V and I, for the quiet sun, plages, sunspot umbrae, and a flare, as well...
Delayed, Line-dependent Reorganization of Pore Oscillations Following a Compact C8.2 Flare Observed by SUNRISE III/SUSI
Magnetic oscillations permeating the solar atmosphere can be altered by flares. This could be due to changes in the atmospheric magnetic waveguide, the...
El Sol desata una tormenta geomagnética excepcional que podría hacer visibles auroras en latitudes inusuales
Una fulguración solar de gran intensidad provoca una tormenta geomagnética severa y un raro evento de partículas El pasado 11 de noviembre, a las 10:04 hora...
Evidence of a White-Light Flare on 10 September 1886
We present evidence of the occurrence of a white-light flare on 10 September 1886. It represents the third such rare event reported in the history of astronomy...
Flares are among the most energetic magnetic solar phenomena. They are often accompanied by ejections of charged particles, which have a direct influence on the...
Infrared spectropolarimetry of a C-class solar flare footpoint plasma
We performed full Stokes spectropolarimetric observations of loop footpoints in the active region NOAA 13363 during a C-class flare with the GREGOR Infrared...
