Not bad. I hope they took some TV footage or still photos of the objects during the EVA; I'd love to see that up close. >This fragment was >probably released in prograde direction meaning that it was moving behind >ISS.(maybe seen by Markus Mehring) I didn't see any trailers in the formation, only two leaders. Upon the surprise of seeing these objects, I ensured to check around the ISS for any others, but without success. For a brief moment I thought I saw a third leader a bit above the two others, towards the ISS, but that was way too faint and too short to be sure, and the new elements don't give a match in that probable position within the formation anyway. Checking that ISS pass (~18:00 UTC) with the elements you gave, I'm quite certain that the brighter one was 26945, which you also saw, and which quite likely is the brightest of the four objects. I would agree to a guessed magnitude of around +5 during that pass. "My" second object of the formation must have been 26946, and it was so faint that the ISS itself would almost outshine it if I kept it in the same FOV; I'd say it was quite well below mag +6. Thinking about it, it also might be worth looking for 26944. Because no one seemingly saw it last night is no certain indication that it can't be seen at all. Looking at the recreated formation, I wouldn't rule out the possibility that it simply would have appeared too close to the ISS to be seen as a standalone object. CU!
