Saw several bright amber/orange lights appear in the sky south of Abilene Texas. One came on and went out and to the east of that one another one came on and went out. Then they came on in pairs, they were very bright orangish color. They came on and went out in the same part of the sky for 15 minutes, no planes in the area ..I saw some planes but these were 100% not planes ...these are the same orange lights that came very frequently earlier this year and last year.
