TITLE: GCN CIRCULAR NUMBER: 31069 SUBJECT: GRB 211106A, GROND observations DATE: 21/11/09 22:36:52 GMT FROM: Ana Nicuesa at TLS Tautenburg <ana@tls-tautenburg.de> A. Nicuesa Guelbenzu, S. Klose (both TLS Tautenburg), and A. Rau (MPE Garching) report: We observed the field of the short GRB 211106A (Tohuvavohu et al., GCN 31049; D'Elia et al., GCN 31051; Ridnaia et al., GCN 31054; Fletcher, GCN 31055; de Wet et al., GCN 31063) centered at the location of the X-ray source #2 (D'Elia et al., GCN 31051, 31068) with GROND mounted at the 2.2m MPG telescope at La Silla Observatory (Chile). Inside the XRT error circle of 'Source #2' no object is detected. At a midtime of November 9, 2021, 02:10 UT, we measure the following 3-sigma AB upper limits: g' > 24.8, r' > 25.0, i' > 24.0, z' > 22.0, J > 21.7, H > 21.1, K > 19.8. Magnitudes are calibrated against the SkyMapper catalog (Wolf et al., 2018, PASA 35, e010) in g'r'i'z' and 2MASS field stars in JHK (Skrutskie et al., 2006, AJ 131, 1163). We thank Paul Eigentaler for excellent support and for performing the observations.
