report on behalf of the MAXI team:
We report the non-detection of MAXI/GSC of the neutrino event IceCube-201209A (GCN #29012).
At 10:39:17 UT on 2020-12-09 (about 23.6 min after the event trigger),
MAXI/GSC scanned the error region of the event at
(R.A., Dec) = (6.8600, -9.2500) (J2000)
with a radius of 65.40 arcmin. No significant excess emission was detected
from the region. A typical 1-sigma averaged upper limit in one scan observation is 20 mCrab at 2-20 keV.
