A new extended gamma-ray source, which was named as Source A, in the southwest of Galactic supernova remnant (SNR) G306.3-0.9 was detected with a significance of ∼13σ at the location of R.A. (J2000) = 13^\rmh 17^\rmm 52^\rms .80, Decl. (J2000) = -63∘ 55' 48" .00 using about 9 years of Fermi-LAT data. In order to investigate this unidentified gamma-ray source in multi-wavelengths, we performed Swift observations of Source A. In this presentation we summarize the published gamma-ray results, report about the recent ToO Swift observations of Source A, and show our preliminary results of the gamma-ray analysis that we conducted using the new X-ray data.
