Ed - thanks for taking the time and interest to respond to my ?
In my (simple) mind, the sun shining 'down' at 23.4N, reflecting back to the satellite over the equator, would result in its glint being observed at 11.7N (In a perfect world). Given whatever variables of angle and tilt, it still seems to appear north of 10N. The ITCZ is pretty much south of that. Cloud cover in that part of the Atlantic looks like a broken mid deck at best, which I would expect to allow the sun to reflect off the water somewhere.
In any case, It USED TO BE observable and NOW it isn't, with the above noted variables largely unchanged.
So... I'm still curious. Or maybe just confused.
