The images from perijove 28 are now available. This is image PJ28_24 in approximately true color/contrast and enhanced versions:
Image 28_24 was obtained shortly before Juno's perijove which makes it a very high resolution image. The resolution is highest (slightly better than 3 km/pixel) in the top center area in the 'central' image (the biggest image). At this high resolution some of the cloud features look rather fuzzy. |

Thanks for the details. Any sense of whether these flashes are comparable in brightness to flashes seen by Galileo?

Any sense of whether these flashes are comparable in brightness to flashes seen by Galileo? It's fairly hard to say. Galileo was taking long time exposures (tens of seconds long, IIRC) and we are taking much shorter exposures with TDI where the flash presumably only lasts as long as one pixel residence time. I guess if you assumed the flash duration was similar one could back out the relative radiometry, but I haven't done that. -------------------- Disclaimer: This post is based on public information only.
