Saw a bright light traveling east, then it stopped.

My wife was on the back porch waiting for the dogs to come in. I was at the kitchen sink 15 feet away down the hall. She called me to "come an look at this light". When I got there, this light, what we thought was the ISS, stopped! It sat there motionlessly for about a minute. Then the light went off for a second then came back on as bright as first witnessed, then went off for a second and came back dimmer. Oh yeah, it was traveling from west to east. It repeated this same pattern of on bright then off, then back on dim, then off, then bright and so on. It was finally obscured by the neighbors trees. About two minutes later, I was looking east over the neighbors roof through a gap in his other trees, I saw a light come on for a second, go off, then came back on to the left, at the same elevation, then went off, and came back on to the right again, at a higher elevation, go off, then come back on to the left at the same elevation then no more. Its like it did a zig-zag, a Z, and that's it. My wife didn't see that part of the display! Hopefully we weren't the only witnesses to this sighting. It was as bright as the space station, which we see often. Satellites, jets, meteors, planes, star-link satellites are all pretty easy to discern! In 2013 we saw 2 fighter jets chasing an object. I sent you a report. Lots of witnesses to object!!! Never heard a word of it except the morning radio shows were bombarded with calls!! May 8th, 2013!!! Thanks for your work!!!
