European Solar Physics Online Seminar Archive

Following an initiative by the University of Oslo the MPS will participate in the "European Solar Physics Online Seminar" series (ESPOS). Details can be found here: https://folk.uio.no/tiago/espos/
The aim of this video conference series is to promote ideas more widely with a specialized audience, and give some exposure to cutting-edge research for students and other young researchers that do not regularly travel to conferences. The ESPOS series is planned to take place every second Thursday at 11am.

ESPOS: Sun-as-a-star flare observations with HARPS-N and SST (Alex Pietrow)

ESPOS
Stellar flares cannot be spatially resolved, which means that we have to extract complex three-dimensional behavior from a one-dimensional disk-integrated spectrum. Due to their proximity to Earth ... [more]

ESPOS: Three dimensional magnetic reconnection: Theory and observations (Jaroslav Dudík)

ESPOS
In the recent decades, three-dimensional modelling of solar flares and eruptions has made a number of predictions that were subsequently indicated by high-resolution imaging observations. These ... [more]

ESPOS: How BRADPIT could help us in flare forecasting through small AR activity monitoring (Augustin André-Hoffmann)

ESPOS
The Sun is a dynamic star, displaying activities ranging from subtle, short-lived events to major coronal mass ejections (CMEs) and powerful flares. Differentiating between “flaring” and ... [more]

ESPOS: Two Distinct Eruptive Events Observed by Metis on October 28, 2021 (Yara de Leo)

ESPOS
On October 28, 2021 the first X-class solar flare of Solar Cycle 25 occurred in active region NOAA AR 12887 with a peak at 15:35 UT. It produced the rare event of ground-level enhancement of the solar ... [more]

ESPOS: First flare observations from SUIT (Soumya Roy)

ESPOS
Solar Ultraviolet Imaging Telescope (SUIT) is the near Ultraviolet imager (200-400 nm) on board the Indian Solar mission Aditya-L1. It was launched on September 2nd, 2023 and was inserted in a halo ... [more]

ESPOS: GATES: A New Network for Synoptic Space Weather Observation (Fallon Konow)

ESPOS
  • Date: Apr 10, 2025
  • Time: 11:00 AM c.t. - 12:00 PM (Local Time Germany)
  • Speaker: Fallon Konow
  • Department of Physics, University of Rome Tor Vergata, Italy; and Department of Physics and Astronomy, Georgia State University, USA
  • Room: https://zoom.us/j/165498165
  • Host: Shahin Jafarzadeh
We present a new network for space weather observation: Global Automatic Telescopes Exploring the SUN (GATES). GATES currently utilizes two primary instruments: the Mojave Solar Observatory (MSO) ... [more]

ESPOS: Spectral resolution effects on the information content in solar spectra (Ivan Milic)

ESPOS
Spectral resolution and sampling present a design trade-off when building spectropolarimetric instruments to observe the Sun with very high spatial resolution. On the one hand, for ... [more]

ESPOS: Solar EUV irradiances, their variations with the solar cycle and a new model (Evangelia Deliporanidou)

ESPOS
Measuring the long-term variability of solar EUV/UV irradiances is needed for e.g. studying the Sun’s influence on space weather, satellite drag and for solar studies. However, direct measurements ... [more]

ESPOS: Decayless kink oscillations of solar coronal loops as a self-oscillatory process (Valery M Nakariakov)

ESPOS
Kink oscillations of the decayless class are detected as small amplitude (< 1 Mm) persistent transverse repetitive displacements of solar coronal plasma loops, occurring without any association with ... [more]

ESPOS: Chromospheric Fibrils in Pores and Mossy Active Region Plage Observed by DKIST, IRIS, and Solar Orbiter (Yingjie Zhu)

ESPOS
Spatial and temporal correlations of chromospheric fibrils and jets with the active region moss emission have been extensively studied since the beginning of this millennium, suggesting a coupling ... [more]

ESPOS: Wind Predict: Modeling the solar corona and its EUV emission (Barbara Perri)

ESPOS
With the increase of space EUV observations (SoHO, SDO, Solar Orbiter and soon the Vigil mission), this diagnostic has become an essential tool to bridge the gap between models and our current ... [more]
