Yamaoka (Nagoya U.), Y. E. Nakagawa (JAMSTEC) report on behalf of the MAXI team: We report the non-detection of the IceCube-161210 event (Blaufuss GCN 20247) by MAXI/GSC. The event region was observed with MAXI/GSC at T0+12 min (T0 = 2016/12/10 20:07:16), and no significant enhancement was detected. A typical 3 sigma upper limit in the 4-10 keV band in a single scan transit is 20 mCrab. We note that the GCN/MAXI NOTICE (EVENT_ID_NUM 732899998) at 02:27 on 11 December 2016 was unintentionally distributed, triggered by an email to the MAXI mailing list to inform this non-detection. We aplogize for the confusion.
