As a passive system which does not produce any light that could interfere with the observations of the fluorescence telescopes of the observatory, it complements the active monitoring systems that use lasers. We discuss the applications of stellar photometry for atmospheric monitoring at optical observatories in general and the particular modes of operation employed by the Auger FRAM. We describe in detail the technical aspects of FRAM, the hardware and software requirements for a successful operation of a robotic telescope for such a purpose and their implementation within the FRAM system.}, organization = {Argentina - Comision Nacional de Energia Atomica}, organization = {ANPCyT}, organization = {Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET)}, organization = {Australian Research Council}, organization = {Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) Fundacao de Apoio a Pesquisa do Distrito Federal (FAPDF)}, organization = {Financiadora de Inovacao e Pesquisa (Finep)}, organization = {Fundacao Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio De Janeiro (FAPERJ)}, organization = {Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) 2019/101512 2010/07359-6 1999/054043}, organization = {Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes (MCTIC)}, organization = {Czech Republic Government}, organization = {Ministry of Education, Youth & Sports - Czech Republic LTT18004 LM2015038 LM2018102 CZ.02.1.01/0.0/0.0/16_013/0001402 CZ.02.1.01/0.0/0.0/18_046/0016010 CZ.02.1.01/0.0/0.0/17_049/0008422 IN2P3/CNRS}, organization = {Centre National de la Recherche Scientifique (CNRS)}, organization = {Region Ile-de-France PNCIN2P3/CNRS}, organization = {Institut Lagrange de Paris (ILP)}, organization = {LABEX ANR-10-LABX-63 ANR11IDEX000402}, organization = {Federal Ministry of Education & Research (BMBF)}, organization = {German Research Foundation (DFG)}, organization = {Helmholtz Alliance for Astroparticle Physics (HAP)}, organization = {Helmholtz Association}, organization = {Min-isterium fur Innovation, Wissenschaft und Forschung des Landes NordrheinWestfalen}, organization = {Minis-terium fur Wissenschaft, Forschung und Kunst des Landes BadenWurttemberg; Italy - Isti-tuto Nazionale di Fisica Nucleare (INFN)}, organization = {Ministry of Education, Universities and Research (MIUR)}, organization = {CETEMPS Center of Excellence}, organization = {Consejo Nacional de Ciencia y Tecnologia (CONACyT) 167733}, organization = {Universidad Nacional Autonoma de Mexico}, organization = {Programa de Apoyo a Proyectos de Investigacion e Innovacion Tecnologica (PAPIIT) Universidad Nacional Autonoma de Mexico}, organization = {Netherlands Organization for Scientific Research (NWO) DIR/WK/2018/11}, organization = {National Science Centre, Poland 2013/08/M/ST9/00322 2016/23/B/ST9/01635 HARMONIA 5-2013/10/M/ST9/00062 UMO2016/22/M/ST9/00198}, organization = {Portugal - Portuguese national funds}, organization = {FEDER funds within Programa Operacional Factores de Competitividade through Fundacao para a Ciencia e a Tecnologia (COMPETE)}, organization = {Romania - Romanian Ministry of Education and Research}, organization = {Program Nucleu within MCI PN19150201/16N/2019 PN19060102 PNIIIP11.2PCCDI20170839/19PCCDI/2018}, organization = {Slovenian Research Agency - Slovenia P10031 P10385 I00033 N10111 FPA2017-85114-P PID2019104676GBC32}, organization = {Xunta de Galicia European Commission ED431C 2017/07}, organization = {Junta de Andalucia SOMM17/6104/UGR P18-FR-4314}, organization = {European Commission}, organization = {RENATA Red Nacional Tematica de Astroparticulas FPA2015-68783-REDT}, organization = {Maria de Maeztu Unit of Excel-lence MDM20160692}, organization = {United States Department of Energy (DOE) DEAC0207CH11359 DEFR0204ER41300 DE-FG02-99ER41107 DESC0011689}, organization = {National Science Foundation (NSF) 0450696}, organization = {Grainger Foundation}, organization = {European Particle Physics Latin American Network}, organization = {UNESCO}, publisher = {IOP Publishing}, keywords = {Large detector systems for particle and astroparticle physics}, keywords = {Real-time monitoring}, keywords = {Optics}, keywords = {Photon detectors for UV}, keywords = {Visible and IR photons (solid-state)}, title = {The FRAM robotic telescope for atmospheric monitoring at the Pierre Auger Observatory}, author = {Aab, A. and Bueno Villar, Antonio and Pierre Auger Collaboration}, }
