Conference/Workshop objectives

The goal of this meeting is to collectively review the advancement in our understanding of solar magnetic fields starting from the fundamental structure size of magnetic fields to global properties of active regions and the Sun as a whole including the heliosphere. This meeting is expected to

(1) provide a platform to present the latest results from the various research infrastructures available within SOLARNET 2 and beyond, be it ground-based telescopes or space missions;


(2) contribute to a better understanding of solar features by bringing together high-resolution and synoptic observations, simulations, analytical theory and instrumentation; and


(3) to discuss the next steps in advancing instrumentation, methods, and theory. To arrive at a cohesive picture of the magnetic Sun, the meeting will be organized according to specific scientific topics and questions, fostering discussions among observers, instrument builders, hosts of data holdings, and theoreticians.

Programme

Key topics

The scientific program will include the following topics:

(1) the "zoo" of quiet-Sun, small-scale magnetic features,

(2) the life-cycle of magnetic structures - from flux emergence to decay,

(3) small-scale energetics - nano-flares, Ellerman bombs, etc.,

(4) the fine-structures of sunspot umbrae and penumbrae,

(5) active regions - stability vs. eruptive events, and

(6) global variations of magnetic fields with the solar cycle.

Conference venue

Location of the Symposium

The conference will take place in "Haus H" on the Telegrafenberg (telegraph hill) in Potsdam, Germany. The Telegrafenberg is within walking distance from central Potsdam, and hosts a campus of research institutes including old observatory buildings, the Einstein Tower, and the Great Refractor. Potsdam has significance in Astronomical history (the Leibniz-Institute for Astrophysics, AIP, is the successor institute of the Berlin observatories, the planet Neptune was discovered here in 1846).

 

Hotel information
Travel information

Travel to Potsdam

Potsdam is located next to Berlin, the German capital, with regular train service connecting the two cities every 10 minutes, and a typical travel time of only 30 minutes between central Berlin and central Potsdam. Berlin is well connected by long-distance trains to Germany and central Europe. The closest international airport is the Berlin-Brandenburg airport (BER). Especially from overseas there might be no direct flights, and one should check flights via Munich, Frankfurt, Amsterdam, or London-Heathrow.

 

Getting to the Venue

From Potsdam's central station it is only a 20-minute walk to the venue. There also is a bus service (route 961) connecting the station to Telegrafenberg, with the final stop right in front of the venue in Haus H. Both the Berlin (BVG) and Brandenburg region (VBB) transportation networks provide smartphone apps that one can use for route planning and for checking time tables.

Potsdam is part of the ‘Berlin ABC’ fare zone, but for travelling within the city limits, buying a ‘Potsdam AB’ ticket is sufficient. A single-fare ticket remains valid when changing the form of transportation (i.e., bus, S-train, tram, regional train). Ticket machines can typically be found at S-train stations and on-board busses and trams. Payment can be normally done either with cash, credit/debit card, or even using contactless payment.

It is also possible to rent a bike at various places in the city, but note that tram tracks and cobblestone roads can make this a bit of a challenge should you not be a regular cyclist.

Abstract:
The non-association of coronal mass ejections with high energetic flares is sparse. For this reason, the magnetic conditions required for the confinedness of major flares is a topic of active research. Using multi-instrument observations, we investigated the evolution and effects of confinedness in an X3.1 flare, which occurred in active region (AR) 12192. The brightenings and decrease of net fluxes near the footpoints of the multi-sigmoidal AR in photosphere and chromosphere, indicative of flux cancellation favouring tether-cutting reconnection (TCR), is observed using the magnetic field observations of HMI/SDO and SOT/Hinode, respectively. The analysis of spectropolarimetric data obtained by the Interferometric Bidimensional Spectrometer over the brightening regions suggests untwisting of field lines, which further supports TCR. Filaments near polarity inversion line region, resulted from TCR of low lying sheared loops, undergo merging and form an elongated filament. The temperature

Abstract:
SolarLab is a container-based observatory for full disk observations of the Sun, to be installed and operated on site of the Thüringer Landessternwarte Tautenburg (TLS). It will be used as a laboratory for instrument development and scientific observations, the requirements for which are derived from SPRING – an envisioned global network of synoptic solar telescopes. The primary instrument is a large tunable Fabry-Pérot interferometer based 2-D spectropolarimeter.
