PJ1 images
By Candy on 2017-09-28 UT
John and Gerald have identified the atmospheric features imaged by JunoCam. This is a timeframe that Jupiter is too close to the sun for amateur astronomers to observe, so we collected a lengthy series of low resolution images with JunoCam dubbed "the marble movie" to provide context for closest approach.

This illumination-adjusted and gamma-stretched version of #6171 shows a candidate for a mesoscale wave train in Perijove-01. Due to the lossy compression, this interpretation may be ambiguous.
JunoCam possibly observed subtle haze features pretty close to the north pole, within the northern CPC polygon.
The attached image is a reprojected version of #6163, illumination adjusted with a 6th degree polynomial over the cosines of solar incidence and emission angle, averaged from a gamma=0.5 and gamma=4.0 enhanced version, then rotated to an approximately vertical terminator, 3/4 of vertical bins subtracted, hipass filtered, and brightness-stretched in a nonlinear way, cropped and annotated.
