US periscopes at night

they would use the SJ radar [if equipt] for a third sounding board so to speak for the all clear..
at 25ft, most SJ's are clear from the water and that represents a very small bump on the water for someone to notice.

of the periscope attack run pictures i have, none are at night, only one was at dusk [a hit on a merchant est..4165 tons..still can make out what they were hitting though]
EDIT: just took another look after all these years, yes, heh, can barely make out the merchant, just sillouete looking

on a clear night sky with the moon in the right spot, one could use the scope i would think.

pops never mentioned using the scope at night though [except for checking all clear i would imagine], all night manuevers were surface attacks or for getting into a favorable position on a convoy.... i guess?
