We've mentioned them before and we will again.
I had previously mentioned a skyrmon structure during part 3 of my ‘magnetic signature of strange radiation’ series on 25th July 2020. And again in my September 30th 2020 Russian conference monopole clutch presentation. The video below animates the observation of ‘Dirac monopoles in a Synthetic Magnetic Field”  which are created in a trapped Bose-Einstein condensate (BEC).
I have argued that the HHO/Ohmasa/Brown Gas can form coherent matter, that is a condensate, and we know from the work of Urutskoev , these can split up to form self-similar micro-ball lighting structures.
I had again referred to a Shankar skyrmion formed in 2018 BEC coherent matter research  in reference to a very similar structure on the MFMPs Hutchison sample 10 - “Ball Burn” made by John Kenneth Hutchison in 1986.
The description of the above video reads:
“Scientists created elusive theorized particle known as the Shankar skyrmion The expets say the quantum 'knot' may mimic the conditions of ball lightning It could finally help to explain the phenomenon, and improve fusion reactors”
So, we can reasonably say that the features on Ohmasa Gas treated 10-Yen coin (2019) and Hutchison Effect exposed ‘Ball Burn’ (1986) sample are likely due to coherent matter BEC states in the form of ball lightning, which mainstream science calls a Shankar skyrmion (2018), and that they have Dirac monopole like aspects to them.
