Shape: Sphere | Duration: 20 Seconds
Source:

Large, bright ball of light, bobbled a bit , then straight up and gone in a second or two.Saw one large, bright ball of yellowish light traveling at a fairly steady pace from west to east along the northern edge of South Park, Colorado. The object appeared to bobble several times while continuing forward. Without notice or any obvious turns, the object went straight up and was completely gone in a second or two. From my vantage point it looked like it disappeared into the right ½ of the Cassiopeia Constellation.
