I have a presentation at the Astro.Soc.So.Africa symposium on Pro-Am collaboration, coming up March 9-12 in Cape Town. The presentation is about the elusive "Magellan's Ghost" light band that goes from the S quadrant of the LMC, through Mensa, crosses Chameleon about 4 degrees to the S, and fades away around Apus. This phenomenon has been discussed periodically on IIS and CN since 2009 and so far no one has satisfactorily explained it. Some of you might remember Timo Karhula's sighting reports on it. I researched and wrote a 70-page paper analysing the possible causes from Galactic cirrus to Magellanic gas and star streaming, and essentially came up with no plausible causes.
There are too few images to go on. I'm asking any of you who work with wide-field imaging to see if you can capture the luminosity patches in the attached image by Hisayochi Kato, but using other filters, exposures, & processing. I could really use a larger palette of images to show at the symposium. I'd be hugely grateful for anything you can provide, and will of course credit the images with the equipment & processing info you provide with them.
Here is a link to my annotated copy of an original by Hisayochi Kato (https://www.flickr.com/photos/145284842@N07/26058690758/in/dateposted/). The emission I would like to see more images is marked with the numbers 1, 2a, 2b, 3.
Thanks much . . .
