Funding Information: The Finnish National Agency for Education (EDUFI) supported this research project through an EDUFI Fellowship. HK was funded by the Research Council of Finland projects 324504, 328898, and 353019. MDS is funded by the Independent Research Fund Denmark (IRFD) via Project 2 grant 10.46540/2032-00022B. KM acknowledges support from the Japan Society for the Promotion of Science (JSPS) KAKENHI grant (JP20H00174) and by the JSPS Open Partnership Bilateral Joint Research Project between Japan and Finland (JPJSBP120229923). NUTS is funded in part by the Instrument center for Danish Astrophysics (IDA). LCOGT network data were obtained through OPTICON (PI Stritzinger, programme ID 2020A/031) and NOAO (PI Bose, programme ID NOAO2020A-017) time allocations. Based on observations made with the Nordic Optical Telescope, owned in collaboration by the University of Turku and Aarhus University, and operated jointly by Aarhus University, the University of Turku and the University of Oslo, representing Denmark, Finland and Norway, the University of Iceland and Stockholm University at the Observatorio del Roque de los Muchachos, La Palma, Spain, of the Instituto de Astrofisica de Canarias. Data were also obtained with ALFOSC, which is provided by the Instituto de Astrofisica de Andalucia (IAA) under a joint agreement with the University of Copenhagen and NOT. This work includes data collected at ESO via programme IDs 1103.D-0328, 0105.D-0511, and 1106.D-0811. We thank the Subaru staff for the data taken by the Subaru Telescope (S19B-054); the authors acknowledge the very significant cultural role and reverence that the summit of Maunakea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain.
