The article Carina Nebula says this star became much harder to see after 'the 1841 Great Ereuption' but doesn't explain what this was [properly. It isn't mentioned at all here. Was WR25 the brightest star in the sky? What did the 'Great eruption' lo0ok like and who observed it? — Preceding unsigned comment added by 79.74.23.38 ( talk) 20:54, 1 April 2017 (UTC)
Article states that WR 25 is 2.4E6 times as luminous as the sun, and has absolute magnitude -7. But 2.4E6 <=> 16 magnitudes brighter (lower) than the sun’s +5 abs mag. That would be -11, not -7.
What gives? Error here? (For comparison, Deneb is listed as 2E5 times solar and -8 abs mag., which agrees with the magnitude scale.) Jmacwiki ( talk) 06:10, 10 July 2022 (UTC)
The article says the star is circled in the photo but I see no circle. 65.75.86.79 ( talk) 11:19, 14 April 2023 (UTC)
