Ellerman Bombs



Hi there, I think that this page could use an update and hoped that maybe you could help as I am quite entrenched in this topic at the moment and do not really know how deep is deep enough/too deep. So I summarize some key points and sources below which I think should be there. As far as I know there are no public domain images of them, but I have a student working on this topic who is finishing her thesis, and we will share some of those images once it is out.

This is the kind of holy grail paper: https://ui.adsabs.harvard.edu/abs/2013JPhCS.440a2007R/abstract

Key points:
https://ui.adsabs.harvard.edu/abs/1956Obs....76..241S/abstract They are also known as IRIS bombs when discussed in the magnesium h&k lines, as those are observed in the IRIS satelite, after https://ui.adsabs.harvard.edu/abs/2014Sci...346C.315P/abstract.



This one again: https://ui.adsabs.harvard.edu/abs/2013JPhCS.440a2007R/abstract

Synethos (talk) 15:22, 2 December 2023 (UTC)
:Hi {{Re|Synethos}} I can totally help out. I should have some time after the new year. I rewrote the lead sentence a little over two years ago referencing Georgoulis et al 2002 ↗, and I have been meaning to add more since then. Thanks for sharing those papers. CoronalMassAffection (talk) 12:05, 10 December 2023 (UTC)
::Hi @CoronalMassAffection, glad to see that these are useful! I think that a lot of stuff can be improved on 'solar wiki', and will try to help out. :) I hope to make a page on surges soonish. Synethos (talk) 13:09, 2 January 2024 (UTC)

Surges


:<small>This topic was split off from {{slink||Ellerman Bombs}}, above.</small>
Hey again {{ping|Synethos}} I definitely agree that there is a lot to be improved. Regarding surges, I recently created the Solar jet ↗ stub article which I intend to have cover jet-like phenomena such as X-ray jets, H-alpha surges, macrospicules, etc. I have thought about how they all should be handled, and I think it would be the most appropriate to have them all together in one article since they are very similar and have been covered as one phenomenon in recent literature (for example, Moore et al 2010 ↗ and Shen 2021 ↗). A quote from Shen 2021:
:"This review mainly focuses on bigger solar jets, including surges, coronal jets and macro-spicules. Although these jet activities are observed at different scales and temperature ranges, they can be viewed as the same type of solar jets owing to their similar observational characteristics and generation mechanism, i.e. magnetic reconnection-dominated jet-like activities with an inverted-Y structure. For smaller, lower-energy jet-like activities such as spicules and dynamic fibrils, their generation mechanisms are still open questions."
I think there would be a lot of overlap if there were to be separate articles, but maybe such an approach would be better. I would appreciate your thoughts on this. CoronalMassAffection (talk) 15:00, 2 January 2024 (UTC)
:Also, using a similar line of reasoning, I think Moreton wave ↗s and EUV wave ↗s (the latter page currently redirects to the Moreton wave article; see this abandoned draft by another user) should also be covered together in one article. CoronalMassAffection (talk) 15:02, 2 January 2024 (UTC)
::I think that it is a good way to start, eventually maybe these things could be split but for now its probably fine to keep them like this.
::As for some more articles, one of mine discusses the density of them. Also the intro is a good place for some general info on surges, as I tend to go overboard on these things.
::https://www.aanda.org/articles/aa/full_html/2022/03/aa42346-21/aa42346-21.html
::I'm not super well versed in moreton waves and EVU, but a dataset that I hope to get soon might have one so I will be reading up. Will post relevant papers once I know them. :)
::Let me know if you'd want some help with any of the pages, or the stuff I described in the above/below topics. Synethos (talk) 16:28, 24 March 2024 (UTC)
:::@Synethos Thanks again :) I will let you know if I encounter any problems. I will hopefully be able to spend some time on this during the summer. CoronalMassAffection&nbsp;𝛿&thinsp;<sup>''talk''</sup><sub>''contribs'' ↗</sub> 17:07, 9 April 2024 (UTC)
::::Hi, not quite surge related but I recently got a paper out on flare ribbon structure including some new features. Do you think that these would be worth a mention on te flare page? All images are open source so that might also help. https://www.aanda.org/articles/aa/full_html/2024/05/aa48839-23/aa48839-23.html Synethos (talk) 22:15, 30 September 2024 (UTC)
:::::Hey @Synethos, I think it would be worth adding. I have not had much time to work on Wikipedia recently, but I hope to dedicate some time this October. I have had a draft of the solar flare article saved locally which I hope to finish and upload sometime in October. I have done some very major restructuring to the initial sections and subsections, and I have added a subsection on flare ribbons, which this paper should be helpful for. Thanks for letting me know. CoronalMassAffection (talk) 22:57, 30 September 2024 (UTC)
::::::Glad to hear, let me know if you need any help. :) Synethos (talk) 14:10, 22 October 2024 (UTC)
:::::::@Synethos Thanks, I'll let you know {{smiley}}. October has passed now, and I still have not had time to work on this. However, I should be able to get to it this month since I have fall break coming up. CoronalMassAffection (talk) 16:50, 5 November 2024 (UTC)

Limbdarkening



Hi, another topic that could use a little polish I think is limb darkening. I think that this figure from my paper would be nice to have there. https://ui.adsabs.harvard.edu/abs/2023A%26A...672L...6P/abstract

Together with an explanation of mu, which is the cosine of the emission angle with respect to the observer. https://astronomy.stackexchange.com/questions/40656/how-to-calculate-the-limb-darkening-mu-value#:~:text=Mu%20will%20be%201%20if,used%20to%20describe%20limb%20darkening.
It is defined as <math>\mu = \sqrt{1 - \left(\frac{\rho}{r_{\text{sun}}}\right)^2}</math>, with rho simply being the radial distance to the calculated point, given in the same units as the radius.

In this paper I show that the limb darkening of spectral lines is different than that of the continuum, varying strongly depending on if it is chromospheric or not, and if it is in LTE or not. https://ui.adsabs.harvard.edu/abs/2023A%26A...671A.130P/abstract

Limb darkening is also a crucial paramater in the calculation of exoplanet transits, which is why this kind of research on the Sun can help with modeling of other stars, and even planets.
https://www.researchgate.net/publication/261636043_Transiting_Planets_Orbiting_Source_Stars_in_Microlensing_Events/figures?lo=1

Probably more can be said, but this would already be a good start. It would be cool if you could take a look and see if you agree with this, as it is probably not OK if I push my own papers there? Synethos (talk) 15:46, 2 December 2023 (UTC)

:Hi again {{re|Synethos}} I think this info should be added as long as we give due WP:WEIGHT ↗ and WP:PROPORTION ↗ to topics covered in the article. Regarding citing your own papers, I would consider looking at WP:SELFCITING ↗ if you have not already. I am not too familiar with the details of limb darkening, so I am not sure how much I can help here; however, I can look more into it. CoronalMassAffection (talk) 12:41, 10 December 2023 (UTC)

Spot, plage/faculae and network definitions



Last one I promise, but since I saw you being interested in these topics specifically, and have been irked for a long time about the improper use of plage and faculae on both wiki, and in some papers. A while ago I have painstakingly assembled the definitions that you can find in the first 1.5 pages of this recently published paper. https://ui.adsabs.harvard.edu/abs/2024MNRAS.527.2940C/abstract Especially the plage one would be great to see a version of on wiki, and to finally get rid of that horrible notion that plage is the same as faculae.

Solar articles



@CoronalMassAffection, I know you raised questions about astronomy/solar articles by @0xReflektor as possible LLM and dubious. High-speed solar wind ↗ was deleted at AfD, what about the other ones? There will be a WP:NPP ↗ drive to reduce the number of unreviewed pages, and I would rather not have reviewers who do not know enough review, and perhaps accept the pages even if they have clear problems. Options are:
#AfD
#Post to WT:Astronomy ↗ to get other opinions (or I can).
#If there are one or three where you can make a clear case I would be OK to draftify those articles.

Ping of @Revolving Doormat who might have useful input as they (perhaps) work in the area Ldm1954 (talk) 14:39, 31 December 2025 (UTC)

:N.B., the articles in question are Wang–Sheeley–Arge model ↗, Potential-field source-surface model ↗, Enlil (heliospheric model) ↗ and Coronal magnetic field ↗ Ldm1954 (talk) 14:45, 31 December 2025 (UTC)
::I will have a look later today. Courtesy ping to @ChildrenWillListen who has a keen eye for this sort of thing. Revolving Doormat (talk) 15:53, 31 December 2025 (UTC)
:::Well, we have the usual "talk about the sources instead of the content" thing at Coronal magnetic field ↗: {{tq|Comprehensive reviews compare [...], emphasizing the need to assimilate diverse observations to reduce model uncertainty}}, and the usual tone issues at Enlil (heliospheric model) ↗: {{tq|The code is named for Enlil, the Sumerian god of wind and storms, '''reflecting the model's focus on solar-wind dynamics'''.}} (emphasis mine). I may look at this later if I find more time. <span style="color:green">Children</span> <span style="color:purple">Will</span> <span style="color:red">Listen</span> (🐄 talk, 🫘 contribs ↗) 01:21, 1 January 2026 (UTC)
::::With this, I strongly suggest we WP:TNT ↗ the Coronal magnetic field ↗ article or alternatively send it to AfD. Revolving Doormat (talk) 15:06, 1 January 2026 (UTC)
:::::I have WP:BLAR ↗ed Coronal magnetic field ↗. CoronalMassAffection (talk) 01:30, 2 January 2026 (UTC)
:@Ldm1954 Thanks for reaching out about this. The relevant articles created by 0xReflektor that I have marked as potentially written by an LLM are as follows.
:# Enlil (heliospheric model) ↗
:# Wang–Sheeley–Arge model ↗
:# NSO Integrated Synoptic Program ↗
:# Potential-field source-surface model ↗
:# <s>Parker solar wind ↗</s> (now a redirect, Special:Diff/1328211181 ↗)
:# Space Weather Modeling Framework ↗
:# Coronal magnetic field ↗
:# <s>High-speed solar wind ↗</s> (AfD, Wikipedia:Articles for deletion/High-speed solar wind ↗)
:For future reference, I have mentioned some of the evidence for LLM writing in User talk:0xReflektor#Reference mistakes and Wikipedia:Articles for deletion/High-speed solar wind ↗. I also just removed a paragraph based on several fabricated, hallucinated, or misattributed quotations in the Wang–Sheeley–Arge model article (Special:Diff/1330502415 ↗).
:My plans for these articles are as follows.
:* Keep or draftify the heliosphere models/software articles (1, 2, 4, and 6 above). I would be willing to carefully review everything and make fixes where necessary at some point in the future.
:* Merge NSO Integrated Synoptic Program ↗ into National Solar Observatory ↗. NISP is not covered in many secondary sources, so I do not think it is notable enough for a dedicated article.
:* Merge Coronal magnetic field ↗ into Solar corona ↗. It does not make sense to have a dedicated article just for the magnetic field IMO.
:Does this work for you? CoronalMassAffection (talk) 23:33, 31 December 2025 (UTC)
::I know nothing about this area, so I am leaving this to you and other experts. My only role would be to draftify an article if there was a consensus for that -- I do not think you have that right. Ldm1954 (talk) 23:42, 31 December 2025 (UTC)
::I agree with @CoronalMassAffection on this, though I am concerned about merging Coronal magnetic field ↗. Several sentences read nonsensically and are cited with three white papers. It is quite a long article to go through and pick apart sentence by sentence multiplied by the WP:REFBOMB ↗. I would rather draftify or send it to AfD, because it's going to take a lot of work to verify and then fix the content that is presently there. Revolving Doormat (talk) 00:46, 1 January 2026 (UTC)
:::Are either of you (@CoronalMassAffection or @Revolving Doormat) going to PROD/AfD these? They are sitting as unreviewed in the physics list. By default I am often the person who Ldm1954 (talk) 11:03, 13 February 2026 (UTC)
::::(I hit reply by mistake, continuing)...the person who reviews physics articles as part of WP:NPP ↗. I dont know enough about the subject to do anything, although obviously LLM is problematic. Ldm1954 (talk) 11:07, 13 February 2026 (UTC)
:::::I will try to look at this this week if @CoronalMassAffection has not gotten to them, I have a lot of grading to do at the moment unfortunately. Revolving Doormat (talk) 15:02, 15 February 2026 (UTC)
::Enlil (heliospheric model) ↗ - I have BLAR'd this one to Heliosphere#Structure ↗. It was mostly gibberish from a number of white papers about space weather and some press releases about the availability of the model. I didn't even see anything worth saving. Revolving Doormat (talk) 19:57, 23 March 2026 (UTC)
::Space Weather Modeling Framework ↗ - BLAR'd this one to Space weather#Models ↗, essentially the same situation as Enlil. Revolving Doormat (talk) 20:01, 23 March 2026 (UTC)
:::@Revolving Doormat Thank you for dealing with these and apologies for abandoning this effort. Some things came up unexpectedly in my personal life, so I have not had a chance to check Wikipedia since January. I support these two BLARs. CoronalMassAffection (talk) 21:52, 10 April 2026 (UTC)
::::Someone unBLAR'd Enlil, without any real justification for it. It might be helpful for us to engage in a discussion to merge to the target and summarize it and show there is a consensus for doing so. And no worries, assumably, we are all very busy and being janitors for AI slop on Wikipedia is a thankless job that one needs a break from. Revolving Doormat (talk) 17:10, 11 April 2026 (UTC)
