SSTP 1977

SSTP (Student Science Training Program) 1977 University of Iowa I was in the Astronomy track and most of the pictures are of my class mates. Here is the perpetual virtual reunion hosted by Larry. I have tried to identify people but it has been 40 years so I may not be all that accurate. Please let me know when I am in error and help me identify people who I really had no clue about.

Anne H, Linda and I think the guy in the middle is named Tom. Please let me know if I have that wrong.
Shoot Off Part 2!
Charlie
Tommy(?), Charlie, Larry and some feet
I really haven't a clue who these gentlemen are. Bruce on the right? Maybe?
Charlie, Pam and Bill

Incognito?
Larry, Hans and I am not sure who that is on the end. Jason? Please let me know if you know who it is.
Tommy? Please let me know if I have the wrong name.
Hans
Jason has apparently wandered in from the set of the old Batman TV show. Or maybe I was going for arty.

Less Incognito...
Larry, Hans and I haven't a clue. Please let me know if you the gentleman on the far right's identity.
Ricky and John
In hindsight, I am not sure why we are picking on the evidently camera shy Anne... Anyways, Pam was clearly more cut out to be a paparazzi than I. I have no clue who the gentleman in the blue shirt is. I'd be happy to correctly identify him.
