flyover that flared enormously

while looking at the full moon my son noticed what looked like the space station flyover which we're familiar with . the object was about 74 degrees height  not quite 90 as it passed.we'd been looking now for about 10-15 seconds and then it flared, the intensity of light grew enormously. the object now was 15- 20 times larger light than before,this lasted about 3 seconds then receded back to the original size. we checked flyover times and there was a thursday 10:12 pm max height was 10 degrees.  It started in the west 10 degrees and disappears 11 degrees above the SSW, so this doesn't fit the flyover we saw.  The flare was the best we've ever seen.  So the question is does the ISS flare ?
