    Was it flagged?

    Yes, looks like nice triple from your large scale image. What do you mean by "Was it flagged?"
    Given how many of these large triples you are finding, we are going to have to re-evaluate, I think, their overall fraction of the population, and how we are going to reliably distinguish these from truly isolated sources. If the core were a little further south, and off the image, I assume this would have just been classified as a #double with #noinfrared . @HAndernach may want to weigh in here, because he's been thinking about how to find those giant sources.

    core = WISE J124503.32+154501.1, but nothing in SDSS; covered by UKIDSS (Kmag=18.2); need big optical telescope to follow up

    AllWISE J124503.32+154501.2:W1234=16.40,15.37,12.10,8.42, thus a likely QSO; From Fig 2 of 2018ApJS..235...10Krogager+
    I estimate z~1.5, thus with 2.62' it may be 1.33 Mpc wide
