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

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)
- 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)
