Joe pointed out to me that the times I listed in the description of the most recent M-63 image were off. I checked the page and found he was right. So I opened the original images and checked the time stamp in each header and found the first image started on 24 April at 0426 UT and the last one ended at 1006. Everyone please check my math but it now looks like what I had thought was 5 hours of luminance data was actually more like 5 hours 40 minutes (less a few minutes for download times). So around 5.5 hours. Perhaps Tyler could chime in with how much time he spend collecting the color photons for his contribution to the image and then we'll know the total time. Thanks Joe for keeping me honest. And thanks too for the kind words in your blog. As I mentioned in the comment I just posted to your blog, "...I love how you take my convoluted verbiage and turn it into something everyone can understand. Well done." patrick
