In order to explore any change caused by the G2 cloud approaching, we have monitored the
flux density of Sgr A* at 22 GHz from 2013 February to 2014 August with a sub-array of the
Japanese Very Long Baseline Interferometry Network. The observation period included the
expected periastron dates. The number of observation epochs was 283 days. We have
observed no significant microwave enhancement of Sgr A* in the whole observation period.
The average flux density in the period is S ν= 1.23±0.33 Jy. The average is consistent with …
