X-Ray Detection of SN 1994W in NGC 4041?
Optical spectra of SN 1994W in NGC 4041 revealed the presence of a dense (Ne>108 cm-3) circumstellar shell. An observation with the ROSAT High-Resolution Imager detected a source, with a luminosity of approximately 8x1039 ergs s-1, coincident with the position of SN 1994W to within 1&farcs;4. The positional coincidence plus the optical evidence for a dense circumstellar shell support the identification of the X-ray source as SN 1994W.
