Talk:Energetic neutral atom

Feedback Request
Energetic neutral atom My first Wikipedia article. I have requested feedback and hope it will be posted here. Some specific questions: Wikipedia "tricks of the trade" and general comments most welcome.Canuck100 (talk) 20:57, 2 November 2009 (UTC)
 * 1) Article started out as short entry on ENAs but grew to encompass ENA Imaging. What are the implications of renaming it Energetic Neutral Atom Imaging? I've thought of breaking it up but it's still a somewhat obscure topic so thought it best to leave it together.
 * 2) Is the article intelligible to a less technical reader?  Is it technical enough for an article of this nature?
 * 3) Is it positive but still neutral?
 * 4) I'd like guidelines regarding when to wikilink a term and how often.  Always?  Only once?  In each section?
 * 5) What quality level is this article.  Aiming for GA - how close is it?

Momentum reversal?
Great article, thank you! Being a non-expert, I struggled to understand the following. If, as stated, 'it is safe to assume that the ENA preserves the vector momentum of the original pre-interaction plasma ion', why can we (or IBEX) detect ENAs from the edge of the heliosphere, generated by solar wind ions streaming away from the sun? Cheers and thanks again! Blolek. — Preceding unsigned comment added by 217.233.221.111 (talk) 08:19, 11 July 2013 (UTC)

Lead section: "high polar altitudes"?
Currently, the 3rd paragraph of the lead section has contained this sentence (emphasis added): "This region of 'space weather' is the site of geomagnetic storms that disrupt communications systems and pose radiation hazards to humans traveling at high polar altitudes or in orbiting spacecraft." When I saw this, I wondered if "altitudes" was incorrect for "latitudes." Going to the "space weather" page, the effect depends on both altitude and latitude. Here's my revision, but it's a bit wordy. If someone has a better idea, that's great: "This region of 'space weather' is the site of geomagnetic storms that disrupt communications systems and pose radiation hazards to humans traveling in airplanes (if both altitude and latitude are high) or in orbiting spacecraft."

Requested Edit
Editors, perhaps you can make a factual addition by creating a new category "Further Reading" and adding a new book that has the words "Energetic Neutral Atoms" in its title. To the best of my knowledge this is the only such book in the world. "Mike Gruntman, My Fifteen Years at IKI, the Space Research Institute: Position-Sensitive Detectors and Energetic Neutral Atoms Behind the Iron Curtain, 2022 ISBN 9798985668704"  See also on Amazon: https://www.amazon.com/Fifteen-Years-Space-Research-Institute/dp/B09RG1CRPS/ref=sr_1_1?crid=2JBPBRX85MA0K&keywords=9798985668704&qid=1645655532&s=books&sprefix=9798985668704%2Cstripbooks%2C104&sr=1-1

Major edits made, further changes requested
I've made some significant edits to this page. The main points here were to make the tone more encyclopaedic and narrow the focus of the article. I've removed some more general information that is beyond ENAs - a paragraph or two with a general description of the Earth's magnetosphere was removed for example.

The Flares / CMEs section was merged with the section on "Creation of ENAs" and re-written for reasons of tone - ENAs are not my field so please check this is still correct and update this with more references if there have been more recent cases of ENA generation from solar eruptions.

I would like to request clarification on the Saturn and Titan sections; these seem to be more general results related to the Cassini mission and I'm not sure how these strictly relate to ENAs. The article states "Several studies have been performed on Titan's ENA emissions." - please expand on this to summarise the results of these studies. The Uranus and Neptune section does not discuss ENAs at all or mention if the Voyager mission carried an ENA imager; please either revise this section to include ENAs or remove it from the article.

I also think that the section "Importance for Earth" might be beyond the scope of the article - perhaps some key points here could be merged into the introduction to contextualise this study and then this section could be removed? SpaceHG (talk) 17:50, 17 November 2022 (UTC)
