Object with blue haze in front and bright white light in back just vanished.

I am a retired 69 year old female Deputy Sheriff and the following is what transpired:  It was late evening and I was sitting on my back porch when I saw, what I thought was a very bright star in the eastern sky.  My next thought was that it was the brightest star that I had ever seen.  I looked for other stars and there were none to be seen.
 I looked back at the object and realized that it was going up and at a slight right angle.  My first thought was that it was a rocket launch from the Cape.  Looking harder at the object I could see a blue haze in front of the object with the bright white light in back of the object.
 At this point I called my sister.  I wanted her to see if she could see it also.  When she answered, I started telling her to go outside.  Not having taken my eyes from the object all of a sudden the white light disappears, a few seconds later there was a huge blue flash and then the blue just faded away.
 I then went on line and according to NASA there had been no launches that day.
