Search for Radio Transmissions 'Oumuama[edit]

Serendipitous MWA Search for Narrow-band and Broad-band Low Frequency Radio Transmissions from 1I/2017 U1 'Oumuama 26 Feb 2018

We found no such signals with non-terrestrial origins and make estimates of the upper limits on Equivalent Isotropic Radiated Power (EIRP) for these three cases of approximately 7 kW, 840 W, and 100 kW, respectively. These transmitter powers are well within the capabilities of human technologies, and are therefore plausible for alien civilizations.

IPA error?[edit]

I'm not at all well-versed in Hawaiian, but I think there is an error in the IPA pronunciation guide. Shouldn't it have a glottal stop at the beginning? See ʻOkina. Wwhhllrr (talk) 15:12, 20 July 2018 (UTC)

I'm gonna go ahead and make this change. Wwhhllrr (talk) 18:10, 1 August 2018 (UTC)

A flat oval[edit]

In this TED Talk, the speaker Karen J. Meech, updates the possible shape to a "flat oval": The Story of ʻOumuamua. (at mark 8 min.) -Rowan Forest (talk) 02:36, 25 September 2018 (UTC)

Yes, similar to the update in the caption artwork File:PIA22357-InterstellarObject-'Oumuamua-ExitsSolarSystem.jpg Tom Ruen (talk) 03:10, 25 September 2018 (UTC)

Mildly active comet?[edit]

Should the "mildly active comet" description be removed from lede and nomenclature sections? I agree it belongs in classification. -- User-duck (talk) 12:48, 15 October 2018 (UTC)

Whatever the classification, we cannot state both in the intro in a contradictory manner. Best to mention in the body of the article that there are a couple of hypotheses. Rowan Forest (talk) 13:42, 15 October 2018 (UTC)
