8 objects taking a 90 degree turn, then aligning in the sky,About 8 dots were moving close one to another in the same direction. As they were moving they were changing distances from one to another. They moved for about 30 second to our right. The first one in the row took an almost 90 degree turn upwards. The other followed. They aligned. The distances between the dots were now equal. After the alignment, the distances got bigger and bigger. They then faded. Two of them reappeared once then faded for good. I kept looking at the sky to for a few minutes to see if they would reappear, they did not.
