Conjunction Alert: Flight Controllers are tracking a conjunction with Object 34984 (Iridium 33 Debris) with two TCAs (Times of Closest Approach) at Friday, 1/13, at 1:38pm, and 3:10pm EST. This object is exhibiting a decay rate approximately 50 times that of ISS which leads to a rather large uncertainty in its predicted position at TCA as well as being sensitive to small changes in the predicted atmospheric density due to solar activity between now and TCA. Solar activity is expected to be quiet with a possibility of increasing to unsettled or even active conditions over the next 24-48 hours. The PC (Probability of Collision) is currently YELLOW. Due to the PC, the late-notification aspect of these conjunctions and the debris’ sensitivity to small changes in atmospheric conditions, Controllers are logging this conjunction as a high-concern level for now and is actively planning a DAM (Debris Avoidance Maneuver) with an estimated TIG (Time of Ignition) of 11:20am on Friday.
