Editing Eta Carinae (section)

===Lesser Eruption===
A new brightening started in 1887, peaked at about magnitude&nbsp;6.2 in 1892, then at the end of March 1895 faded rapidly to about magnitude&nbsp;7.5.<ref name="frew"/> Although there are only visual records of the 1890 eruption, it has been calculated that η&nbsp;Carinae was suffering 4.3&nbsp;magnitudes of visual extinction due to the gas and dust ejected in the Great Eruption. An unobscured brightness would have been magnitude 1.5–1.9, significantly brighter than the historical magnitude. Despite this, it was similar to the first one, even almost matching its brightness, but not the amount of material expelled.<ref name=humphreys1999>{{cite journal |last1=Humphreys |first1=Roberta M. |author1-link=Roberta M.
