Yes, it can be found on the TCE list but only with one planet. The event described here is not on the list.

Yes, you are right there is another possible transit feature in addition to the TCE/KOI entry of P=56x. And there might be a similar repeat with a period around 1095.96 BKJD (+/-). The duration could be an issue for such a long period however, unless it is a high-impact or grazing transit (or a background stellar transit perhaps). But the estimated planet size could be ok. I didn't check for glitches or cosmic rays however. But looks like you mentioned it’s in the SAP_FLUX. Also only two possibles more speculative that more repeats, of course. But always a chance with something similar in duration. And another more proven transit in the same system helps which is an HZ candidate from what I saw on a quick paper search. Wowie. Anyway, just an opinion to add to yours. Hope it helps.
s1=145.10682 p1=56.05628 d1=0.19574 (4.69776 hrs)
s2=325.098 p2=1095.96 d2=0.31 (7.44 hrs)

Thank you! I have already added a chart concerning glitches and the SAP_QUALITY seems to be clear (see LC(SAP_FLUX)/SAP_QUALITY above).
Using Kian's PC with the following properties: flux:0.005098, mag 15.849, teff 3743, star radius/mass 0.491/0.68, transit duration 8.33 h I get a period of 551.6 days which apparently is quite off.

Well, 552 is about half of 1096, so this looks like it might be a case of the true period being an integer multiple (2) of the observed one. This predicts a transit around t = 873 days. However, none are observed; the transit at t~874 d is due to the 56-day object. So there seems to be something else going on here.

Actually it would be around ~877 BKJD but this location is a known glitch and as expected we unfortunately see a data break in the raw data:

Ohhh, just occurred to me I saw another possible transit around 1420-1421 BJD:
http://talk.planethunters.org/#/boards/BPH0000008/discussions/DPH000052fSorry about that but a glitch seems more likely now... Just busier than usual with the holidays ahead here, but still, my apologies. Mark
p.s. not to worry though... I am (as usual) undeterred, and we will press on with more possible finds at another time.

No problem 😃. According to the link I am still not sure and I would like to see a couple of more instances before we give them glitch status.
