External links modified

Hello fellow Wikipedians,

I have just modified one external link on Gamma Microscopii. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive http://www.webcitation.org/6630AbtJZ?url=http%3A%2F%2Foutreach.atnf.csiro.au%2Feducation%2Fsenior%2Fastrophysics%2Fphotometry_colour.html to http://outreach.atnf.csiro.au/education/senior/astrophysics/photometry_colour.html

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

Nearest approach

Why is the visual magnitude given for the uninteresting distance of 6ly, but not for the very interesting closest distance of 1.14ly? Fig (talk) 19:26, 31 October 2018 (UTC)

I presume it is because the distance (and therefore visual magnitude) at closest approach is highly uncertain - the 1.14ly figure appears to be one end of the error bar. I infer that the intent of the paragraph is to communicate that it shone in Earth's sky at a visual magnitude of -3.0 or brighter for 200000 years and that, at its closest, it reached between about 0.8 and 3.3 magnitudes brighter than that. The former would leave it slightly inferior to Venus at the latter's brightest, the latter would make it truly spectacular: even a casual observer would notice it in the daylight sky in favorable conditions. 213.78.82.8 (talk) 20:05, 4 June 2021 (UTC)
