Outside of the home, observing the sky and looked to the WEST and saw a star like object in the shape of a cylinder. It was bright, and had a off/on light sequence of red near the top and blue near the bottom of the object flashing off/on. On top of the object a bright light would come on/off looking like some type of dome light, then go off after 3-5 seconds and same type of light on the bottom of the craft would do the same thing. After observing the object at about 35 to 40 degree angle, around 11:34 a beam shout out to the South like a search light for no more than 5-6 seconds, but at the precise time of 11:37 a object departed the main object looking something like a aircraft and was giving off a haze blue light, the object departing was noticed for 4-7 seconds and disappeared, conclusion it went into another dimension.The main object still there and doing the same red/blue light and dome type light on top off/on and the bottom white light doing the same off/on.At 11:50 I ended the observation and went back to my home from the yard area. I happened to awaken around 3 am and observed out the bedroom window NO object , it had departed.Location of this observer is the country side, nearest town 8 miles.NOTE" during a one week period if the sky is clear one can observe this object or others in about the same areas or additional objects of the similar description, but this observation is the first observation of seeing an object depart from the main object.
