Pulsing red object moving west to east at airliner speed without standard aircraft lighting.My wife and I were walking our dog when I noticed a red (lit) object moving in the Western sky. I was intrigued because the lighting was non standard for an aircraft (I am an airline pilot, 39 years of flight experience). The object seemed to dip and then rise again before proceeding eastbound at a perceived speed similar to an airliner. Pulsing, bright, red lighting. No strobes or landing lights typical of a departing jet. No noise was heard. Continued on a straight easterly heading before disappearing. Note: this is my first EVER report. I have never seen anything like this!
