Title: “G-band and Hard X-ray Emissions of the 2006 December 14 Flare Observed by Hinode/SOT and RHESSI” by Kyoko Watanabe (Institute of Space and Astronautical Science[ISAS], JAXA), Sam Krucker, Hugh Hudson (Space Science Laboratories, University of California, Berkeley), Toshifumi Shimizu (ISAS/JAXA), Satoshi Masuda (Nagoya University), Kiyoshi Ichimoto (Kyoto University)
The Astrophysical Journal, No.715, pp. 651-655, 2010.

Hinode site press release which explain what was discovered: they caught a flare being formed and tied this with x-ray emissions from the same regions.

All I have done is difference the image pair then do some image enhancement, the critical step being rebalancing RGB which makes a pleasing image as well as bringing out detail.

I thank the authors for freely providing the image pair.

Some careful digging found the paper and no paywall. (pdf)

    Very nice work. Image grabbed and saved. Mercy buckets!

    As art Brian it needs gamma and maybe correlation stretching, many possibilities to make it more acceptable, is a call on what is best. There is crazy detail in the background “cells” where some fancy processing could change things again. The solar images are nuts, maybe the factual nature of life, chaotically ordered.

    What I noticed, maybe not particularly apparent in that version is how the cell structure looks to the human eye melted where the flare has operated. Perhaps the conditions do disrupt the structure.

    Time to remember how this is produced:

    Does anyone know how to stop that really annoying “thing” that pops up at the bottom of many WordPress blogs recently? I seems to have no purpose at all, and on an iPhone makes a significant area of the screen unusable.

  5. tchannon says:

    As a hosted blog this is out of the control of Rog (Tallbloke) or Tim (myself).

    Turn off scripting.
    Block the script involved, if you can find it (*).
    Log in the WordPress but that turns off one set of annoyances and turns on another.

    * Probably within a list of including scripts named highlander

    We have and continue to discuss moving the blog to other software/servers/management company but at the moment WordPress is the best of a poor bunch.

    Hi everyone
    Good score for the ‘magnetics’ on the solar thread, not a ‘nonsense’ any more now accepted as based ‘on the flimsiest grounds’.
    It looks like as ‘where vukcevic boldly goes, NASA cautiously follows’

    @Vukcevic: Congratulations! You have magnetized them.

    If it’s scripting, try loading Ghostery. Basically a tracker blocker, it has many capabilities if you explore Options.

    I’m not seeing any intrusive bottom-of-screen WP stuff, in any case.
