Traditionally\, solar instrumentation has accomplis hed this by recording slices through the spatio-spectral domain\, and scan ning in the missing dimension. A Microlensed Hyperspectral Imager (MiHI) i s an instrument that is able to observe a spatio-spectral cube instantaneo usly\, thus eliminating the need to scan. This increases the photon effici ency of the observations\, and with the aid of state of the art cameras al lows for the acquisition of very high cadence data. Combined with image re storation\, high resolution spectra with a spatial resolution close to the diffraction limit of the telescope can be obtained at a cadence of less t han one second\, in all four Stokes parameters. The talk covers the basic principle of operation\, data extraction and restoration\, and some exampl es of data recorded at the Swedish Solar Telescope.\n\nhttps://meetings.ai p.de/event/24/contributions/356/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/356/ END:VEVENT BEGIN:VEVENT SUMMARY:DKIST observations of small-scale\, internetwork magnetism in the quiet Sun DTSTART;VALUE=DATE-TIME:20230508T152500Z DTEND;VALUE=DATE-TIME:20230508T154000Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-299@meetings.aip.de DESCRIPTION:Speakers: ryan campbell (queen's university belfast)\nA new er a of solar physics commences with observations of the quiet Sun using the 4-metre Daniel K. Inouye Solar Telescope/Visible Spectropolarimeter (DKIST /ViSP). We present full-Stokes observations at a spatial resolution of 0.1 ’’\, taken during DKIST’s cycle 1 Operations Commissioning Phase\, i n the Fe I 630.1/630.2 nm and Ca II 854.2 nm lines\, allowing us to examin e small-scale magnetism in the photosphere and chromosphere. We focus on t he photospheric diagnostic and use the Stokes Inversion based on Response functions (SIR) code to invert the Fe I line pair. This allows us to chara cterize the thermodynamic\, kinematic and\, crucially\, magnetic propertie s of the pervasive small-scale magnetic features present in the data in th e photosphere – namely\, constraining their magnetic field strengths\, f illing factors\, and magnetic inclinations. We reveal small-scale magnetic structures\, including magnetic bi-poles/loops\, in unprecedented detail. \n\nhttps://meetings.aip.de/event/24/contributions/299/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/299/ END:VEVENT BEGIN:VEVENT SUMMARY:First light and science of the UCoMP instrument of MLSO: the magne tic and thermodynamic morphology of CME precursors and eruptions DTSTART;VALUE=DATE-TIME:20230508T151000Z DTEND;VALUE=DATE-TIME:20230508T152500Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-301@meetings.aip.de DESCRIPTION:Speakers: Maurice Wilson (NCAR High Altitude Observatory)\nTh e mechanism for the storage and release of magnetic energy in coronal mass ejections (CMEs) remains a major unsolved problem of Heliophysics. Thus\, observations of the coronal magnetic field before\, during\, and after th e eruption are crucial both for scientific progress and space weather pred ictions. We use the newly built Upgraded Coronal Multichannel Polarimeter (UCoMP) instrument from the Mauna Loa Solar Observatory (MLSO) to study t he magnetic and thermodynamic morphology of CME precursors and eruptions. With this coronagraph's 20-cm aperture and field of view extending from 1 .05 to 2.0 solar radii\, we determine the magnetic field orientation of pr e- and post-CME coronal loops using Stokes Q and U parameters as derived f rom the linearly polarized radiation observed from the Fe XIII 1074 nm spe ctral line. To ascertain the density\, temperature\, and ionization distr ibution of the hot plasma\, we compare and contrast the structures seen at 1074 nm with the coronal features observed by UCoMP at the Fe X 637 nm li ne\, the Fe XV 706 nm line\, the Fe XI 789 nm line\, and the Fe XIII 1079 nm line. In this study\, we use several CME precursors and eruptions as e xamples for showcasing the unique capabilities of UCoMP\, which will infor m the future of ground-based coronograph polarimeter observations that wil l eventually be performed with the COronal Solar Magnetism Observatory (CO SMO).\n\nhttps://meetings.aip.de/event/24/contributions/301/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/301/ END:VEVENT BEGIN:VEVENT SUMMARY:SunDish Project: Single-Dish Solar Imaging and calibration in K-ba nd with the INAF Radio Telescopes DTSTART;VALUE=DATE-TIME:20230508T145500Z DTEND;VALUE=DATE-TIME:20230508T151000Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-302@meetings.aip.de DESCRIPTION:Speakers: Sara Mulas (INAF-OAC)\nThe SunDish project aims to m ap and monitor the Sun at high radio frequencies with the Italian Sardinia (64-m) and Medicina (32-m) Radio Telescopes in the K-band range (18-26 GH z)\, up to 100 GHz in perspective. Since the two instruments were not orig inally designed to observe the Sun\, a new solar radio imaging system was implemented. To date we acquired more than 350 solar maps with resolutions in the 0.7-2 arcmin range\, filling the observational gap in the field of chromospheric imaging at these frequencies to date.\n\nObservations of th e brightness temperature of the solar atmosphere in the radio band can map plasma processes that produce free-free emission in the local thermodynam ic equilibrium and gyromagnetic phenomena\, providing a probe of physical conditions in a wide range of atmospheric layers both for quiet and active regions.\n\nAs a first early science result of the project\, we present t he first catalog of radio continuum solar imaging observations with Medici na 32-m and SRT 64-m radio telescopes including the multi-wavelength ident ification of active regions\, their brightness and spectral characterizati on. The interpretation of the observed emission as thermal bremsstrahlung components combined with gyro-magnetic variable emission pave the way to t he use of our system for long-term monitoring of the Sun. Single-dish radi o imaging represents an ideal technique to perform accurately calibrated s olar observations. We obtained obtained unprecedented and very precise cal ibrated measurements of the Quiet Sun in the K-band affected by a mean rel ative error of 3%.\n\nThrough systematic monitoring of the Sun\, our syste m can provide accurate measurement of the brightness temperature of the ra dio-quiet Sun component\; characterization of the flux density\, spectral properties and long-term evolution of dynamical features (active regions\, coronal holes\, loop systems\, streamers\, and the coronal plateau)\; pre diction of powerful flares through the detection of peculiar spectral vari ations in the active regions\, as a valuable forecasting probe for the Spa ce Weather hazard network.\n\nhttps://meetings.aip.de/event/24/contributio ns/302/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/302/ END:VEVENT BEGIN:VEVENT SUMMARY:FRANCIS: a fibre-fed prototype integral field unit for the near-UV DTSTART;VALUE=DATE-TIME:20230508T143000Z DTEND;VALUE=DATE-TIME:20230508T145500Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-353@meetings.aip.de DESCRIPTION:Speakers: David Jess (Queen's University Belfast)\nThe Fibre-R esolved opticAl and Near-ultraviolet Czerny-Turner Imaging Spectropolarime ter (FRANCIS) was developed as a low-budget prototype integral field unit for the upcoming Indian National Large Solar Telescope. At its core\, FRAN CIS is a fibre-fed Czerny-Turner spectrograph that is designed to work wit hin the spectral range of 350-700 nm\, hence enabling high cadence and spa tially resolved studies of spectral lines in the near-ultraviolet. In the summer of 2022\, FRANCIS was shipped to the Dunn Solar Telescope in the Sa cramento Peak mountains\, New Mexico\, USA\, where it was commissioned and underwent science verification. The first-light observations are very enc ouraging\, with the final data products suitable for mainstream scientific exploitation. Here\, I will overview the history of the instrument\, prov ide a snapshot of its strengths and associated weaknesses\, indicate a tim escale for future upgrades\, as well as provide samples of its spectral im aging capabilities. At present\, FRANCIS is available as a common user ins trument at the Dunn Solar Telescope\, so I will also highlight how interes ted parties can become involved with future observing campaigns.\n\nhttps: //meetings.aip.de/event/24/contributions/353/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/353/ END:VEVENT BEGIN:VEVENT SUMMARY:Overview of SO/PHI-HRT in the Nominal Mission Phase: data and resu lts DTSTART;VALUE=DATE-TIME:20230508T125000Z DTEND;VALUE=DATE-TIME:20230508T130500Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-303@meetings.aip.de DESCRIPTION:Speakers: Daniele Calchetti (Max Planck Insitute for Solar Sys tem Reaserch (MPS))\nThe ESA and NASA Solar Orbiter mission started its no minal mission phase in November 2021. Three perihelions and nine remote se nsing windows have been successfully completed\, providing data from all t he instruments on board the spacecraft. The Polarimetric and Helioseismic Imager (SO/PHI)\, one of Solar Orbiter's remote sensing instruments\, is t he first magnetograph to observe the Sun from outside the Sun-Earth line. Most of the data acquired by the High Resolution Telescope (SO/PHI-HRT) ha s been placed on the Solar Orbiter Archive (SOAR) and are available to the whole scientific community. The excellent polarimetric sensitivity of the instrument and the absence of aberrations induced by the Earth’s atmosp here provide an ideal scenario to study the photospheric dynamics and magn etism of the Sun. The talk will introduce the SO/PHI-HRT instrument and de scribe the data that has been released so far. The processing of the data will also be shortly discussed. We will then present some of the scientifi c cases that have been addressed\, either with standalone observations per formed by the instrument\, or with data combined with observations made by other Solar Orbiter instruments\, or with data gathered by instruments on other spacecrafts or on ground.\n\nhttps://meetings.aip.de/event/24/contr ibutions/303/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/303/ END:VEVENT BEGIN:VEVENT SUMMARY:Exploring the inner heliosphere with combined LOFAR and Solar Orbi ter / Parker Solar Probe observations DTSTART;VALUE=DATE-TIME:20230508T123500Z DTEND;VALUE=DATE-TIME:20230508T125000Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-300@meetings.aip.de DESCRIPTION:Speakers: Christian Vocks (Leibniz-Institut für Astrophysik P otsdam (AIP))\nThe phenomena of the active Sun\, like flares and coronal m ass ejections (CMEs)\, have significant influence on Earth and our technic al civilization. This is usually referred to as "Space Weather". Flares an d CMEs accelerate electrons and ions to high energies. These particles are studied both remotely by ground- and space-based telescopes\, and in situ by spacecraft. Energetic electrons emit radio waves as they move through the coronal plasma. This plasma emission is observed by radio telescopes\, e.g. LOFAR. Since the frequency decreases with plasma density higher in t he solar atmosphere\, and radio waves below 10 MHz cannot pass Earth's ion osphere\, spacecraft are needed to continue observations further into inte rplanetary space. They are also required for measuring energetic particles and observations of X-ray emission in the corona. Therefore\, combining L OFAR and spacecraft data provides new insights into the physical processes in the region where the solar corona turns into the solar wind. Parker So lar Probe (PSP) and Solar Orbiter are two missions currently exploring the inner heliosphere. I'll present LOFAR observing campaigns during PSP and Solar Orbiter perihelia\, that cover the Sun and it's surroundings by maki ng use of LOFAR's capability of running multiple observing modes in parall el\, and show how they connect the corona with the heliosphere.\n\nhttps:/ /meetings.aip.de/event/24/contributions/300/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/300/ END:VEVENT BEGIN:VEVENT SUMMARY:The European Solar Telescope (EST): instruments and science DTSTART;VALUE=DATE-TIME:20230508T121000Z DTEND;VALUE=DATE-TIME:20230508T123500Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-365@meetings.aip.de DESCRIPTION:Speakers: Rolf Schlichenmaier (Leibniz-Institut für Sonnenphy sik (KIS))\nThe EST is a project aimed at studying the dynamic magnetic co nnectivity of the solar atmosphere\, from the deep photosphere to the uppe r chromosphere. A polarimetrically compensated telescope with integrated m ulti-conjugated adaptive optics will feed a suite of spectropolarimetric i nstruments that allows to simultaneously observe the different layers of t he solar atmosphere. In this talk\, I will present the concept for the lig ht distribution and the instrument suite which intends to significantly im prove our capabilities to address critical science cases in our field such as: How does the magnetic field emerge into the photosphere? How does it evolve\, interact\, and rise in a convectively stable stratification? What is the interplay between the magnetic field\, reconnection processes\, ra diation\, waves\, and the transport of energy into higher layers?\n\nhttps ://meetings.aip.de/event/24/contributions/365/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/365/ END:VEVENT BEGIN:VEVENT SUMMARY:Welcome DTSTART;VALUE=DATE-TIME:20230508T120000Z DTEND;VALUE=DATE-TIME:20230508T121000Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-415@meetings.aip.de DESCRIPTION:https://meetings.aip.de/event/24/contributions/415/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/415/ END:VEVENT BEGIN:VEVENT SUMMARY:DKIST instruments and science DTSTART;VALUE=DATE-TIME:20230511T091000Z DTEND;VALUE=DATE-TIME:20230511T093500Z DTSTAMP;VALUE=DATE-TIME:20240704T115546Z UID:indico-contribution-59-407@meetings.aip.de DESCRIPTION:Speakers: Thomas Rimmele (National Solar Observatory)\nhttps:/ /meetings.aip.de/event/24/contributions/407/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/407/ END:VEVENT END:VCALENDAR
