The unusual supernova remnant candidate G357.7 - 0.1 and the compact source G357.63 - 0.06 have been observed with the Very Large Array at 1.4 and 8.3 GHz .
The H 92 \alpha line ( 8.3 GHz ) was detected from the compact source with a surprising velocity of \sim - 210 km s ^ { -1 } indicating that this source is an H ii region , is most likely located at the Galactic center , and is unrelated to the SNR .
The H i absorption line ( 1.4 GHz ) data toward these sources supports this picture and suggests that G357.7 - 0.1 lies farther away than the Galactic center .
