Gents, further to the activity this day - for completeness of logs, can anyone with better optics than me confirm which Sentinel was in the middle of the airfield and which Rivet Joint was out?
The RJ will have been 665 as the other two are stateside.
694 has been the most active Sentinel of late, possibly that one. Near enough impossible to read off Sentinels from that distance from the a15.
Made out 690 from photos on the Alpha dispersal but the middle remained a mystery. Even with my old Kowa 32x scope (got pinched), with that haze reading wouldn't have happened. Appreciate the good gen on 665 and 694.
