SN 1895B was a supernova event in the irregular dwarf galaxy NGC 5253, positioned 16″ east and 23″ north of the galactic center.

[4] The supernova was discovered by Williamina Fleming on December 12, 1895 after noticing an unusual spectrum on a photographic plate taken July 18, 1895, and was initially given the variable star designation Z Centauri.

[2][6] The light curve is consistent with an event that began ~15 days before the discovery plate was taken,[4] and this indicates the supernova reached a peak visual magnitude of up to 8.49±0.03.

[2] After the light faded, the remnant has remained undetected at any wavelength,[4] including X-ray and radio.

[2] This suggests the expanding remnant is meeting a low density of surrounding interstellar material, which would be consistent with certain double white dwarf merger scenarios.
