For KIS time submit your proposal to \url{kis_tac@leibniz-kis.de}. For Spanish time access the web page at: \url{http://research.iac.es/OOCC/solar-cat/}. %For the International Time Programme (ITP/CCI), send you proposal to \url{east-tac@astro.su.se}. \bigskip For more information consult: \begin{center}\large \url{https://www.leibniz-kis.de/en/observatories/gregor/observations-with-gregor/} \\ %and \\ %\url{https://www.leibniz-kis.de/en/observatories/gregor/gregor-instruments/} \end{center} For questions please contact KIS info mail: \quad \texttt{\url{kis_tac@leibniz-kis.de}} \vspace{7ex} \centerline{{\Large\bf Proposal Deadline: 30 January 2026}} \vspace{7ex} \vfill The applicant acknowledges the following notes: \begin{enumerate} \item The GREGOR TAC will allocate observing days including weekends. The observer team will be able to conduct observations \textbf{on-site or remotely} with the support of observing assistants present at GREGOR. \item The PI is committed to cooperate archiving the raw data. \item The PI agrees to follow the instructions for observers, which include safety precautions and to read manuals before the observations. \item The PI commits her/himself to submit an observing report within two weeks after the campaign focusing on the telescope and instrument performance. For efficient use of telescope time, the technical staff needs feedback about the performance of the telescope and instruments. \item The PI agrees that the data are openly available after a proprietary phase of 12 months. For PhD theses, the proprietary phase is prolonged to 2 years. The PI is encouraged to share the data with consortium members and with external scientists on a collaborative basis. \item All publications based on GREGOR data have to acknowledge GREGOR according to the template on our website. %The GREGOR papers to be cited are Kleint et al. A\&A 641, A27 (2020) and the relevant papers from the special AN issue 'Astronomical Notes, Volume 333, 2012, Number 9' including Schmidt et al. 2012, AN 333, p796 (DOI: 10.1002/asna.201211725) and the instrumentation papers. \end{enumerate} \newpage %========================================================================= % Beginning of form: to be completed %========================================================================= \section{Title of Project:} % Please specify title of program above this line %------------------------------------------------ \section{Applicants} \hrule \begin{tabular}{ll} \rule{5.0cm}{0.0cm} & \rule{10.0cm}{0.0cm} \\ [-0.4cm] {\bf Principal Investigator}: & % Principal Investigator's name above this line %---------------------------------------------- \\ [0.2cm] {\bf Affiliation:} & % Please specify PI's institute above this line %---------------------------------------------- \\[0.2cm] {\bf Email address:} & % Please specify PI's email address above this line %-------------------------------------------------- \\[0.2cm] {\bf Co--Investigators(s):} & % Please specify name(s) of co-investigator(s) above this line %------------------------------------------------------------- \\[0.2cm] {\bf Affiliation(s):} & % Please specify affiliation(s) of co-investigator(s) above this line %-------------------------------------------------------------------- \\[0.2cm] {\bf Email address(es):} & % Please specify email address(es) of co-investigator(s) above this line %----------------------------------------------------------------------- \\[0.5cm] \end{tabular} \hrule \checkbox{-} We/I apply for time under the KIS Time.

Please make sure that all necessary information is provided and that no identifying information about the PI/team is included.) \par } \subsection{Previous data} {\scriptsize \noindent (If you were awarded observing time for a similar topic previously, summarise previous results or show the progress of your current analysis and justify why you need more observing time. If archive data are available, please justify why they cannot be used for your study.) \par } \newpage \section{Observing requests:} \subsection{Setup requested:} {\scriptsize \noindent (Please include the required instrument setup description and fill the checklist table based on available instruments (see below) {\bf GRIS slit-scanner modes of operation: } -One spectral arm at any arbitrary wavelength between 0.75-1.30\,$\mu$m or 1.55-1.80\,$\mu$m. -Two simultaneous spectral arms at 1083 and 854.2 nm, with spectral lines of interest centered on the detectors. -Two simultaneous spectral arms at 1281.8 and 854.2 nm, with spectral lines of interest centered on the detectors. -Three simultaneous spectral arms at 1083, 854.2, and 770 nm, with spectral lines of interest not centered on the detectors. All configurations support full-Stokes polarimetric measurements across the selected wavelengths. {\bf GRIS IFU:} Not available in 2026A. Will be available in 2026B. {\bf HiFIplus:} Fast context imaging below 740 nm (below 650 nm if using H-alpha Slitjaw): blue continuum, G-band, H$\alpha$ narrow/broad, TiO, Ca II H {\bf Off-limb AO:} GREGOR has a new AO mode (H-alpha-AO) which allows to lock the AO off-limb on prominences (if the prominence shape permits). This mode is offered on a shared-risk basis and allows to use of HiFI H-alpha 656 narrowband and GRIS in the slit or IFU mode. %- ZIMPOL: In collaboration with IRSOL, high-precision spectropolarimetric observations with the ZIMPOL polarimeter are offered in service mode for projects requiring a short observing time (up to a few hours). The available spectral range is 4250 \AA\ - 6800 \AA\, and the spectral window is a few Angstroms (depending on order and wavelength). {\bf SJ:} Please state whether you plan to use the slit jaw (SJ) imaging system. If applicable, describe any non-standard setup. Please also list the foreseen observing mode (FOV, exposure times, duration of raster, required S/N, targets, ...) )\par } \begin{table}[h] \begin{tabular}{|l|c|c|c|c|c|} \cline{2-6} \multicolumn{1}{c|}{} & 0.75-1.30\,$\mu$m & 1.55-1.80\,$\mu$m & \parbox{4.5em}{\vspace*{1ex}1083.0 + \\ 854.2 nm \vspace*{1ex}} & \parbox{4.5em}{1282.0 +\\ 854.2 nm} & \parbox{8.5em}{1083.0 + \\ 854.2 + 770\,nm} \\ \hline \multicolumn{1}{|l|}{\textbf{GRIS/Slit}} & & & & & \\ \hline %\multicolumn{1}{|l|}{\textbf{GRIS/IFU}} & \multicolumn{5}{|l|}{IFU not offered in 2026A.
