- New images covering the entire remnant provided
- Hypothesis suggests partial overlap between G189.6+03.3 and IC443's emission
- Authors divide G189.6+03.3 into several regions and extract spectra from each region

## Summary

This study focuses on two supernova remnants, G189.6+03.3 and IC443, located in a region rich in gas and dust near the HII region S249. While IC443 has been extensively observed in various bands, there is a lack of observations on G189.6+03.3, which was discovered in 1994 with ROSAT and is much weaker than IC443. The authors take advantage of the new dataset provided by the X-ray telescope eROSITA onboard the Spectrum Roentgen Gamma (SRG) mission to characterize G189.6+03.3 more thoroughly. They provide a full spectral characterization of its emission for the first time and present new images covering the entire remnant. One hypothesis suggests that G189.6+03.3 partially overlaps with the emission of IC443. To test this scenario, the authors divide G189.6+03.3 into several regions and extract spectra from each region.
