Created talk-page for the AT2018cow article[edit]

Created talk-page for the AT2018cow article - Enjoy! :) Drbogdan (talk) 01:04, 23 June 2018 (UTC)[reply]

Was intensity still rising at discovery[edit]

Has there been any calculation of when the SN started ? A graph (or URL) would be great. If we have a narrow time window (for the prediscovery event) could we check the recordings from a single GW detector (even though we normally need two online at the same time) ?

@Rod57: Good questions - the first detection of AT2018cow seems to be on 16 June 2018^[1] - some form of monitoring of the location (RA:244.000927647 / DEC:+22.2680094118)^[2] seems to have been done from 11 June 2018 to 3 July 2018, as noted (and cited), in the AT2018cow article - the USA LIGO detectors were down for service upgradings^[3] - don't know if any other GW detectors (esp Virgo in Italy) were operational at the time of the event - hope this helps in some way - in any case - Enjoy! :) Drbogdan (talk) 12:40, 4 July 2018 (UTC)[reply]

where does the cow part of the name come from?[edit]

Do astronomers attach random words to the names of events like this, or is it random letters? If the latter, does that mean it was a coincidence that this time the letters just happened to spell a word? Thanks, —Soap— 17:50, 18 October 2023 (UTC)[reply]

Not random. Sequential. Starting with single capital letters: A, B, C, etc. Then two lowercase letters: aa, ab, etc. Then after zz, three lowercase letters: aaa, aab, etc. That's a lot of supernovae! Lithopsian (talk)
