Temporal Badge Ranks indicate how long a person has been doing something. The symbol of the Sun is modified to show progress under a month. Thus if a person does something for less than one day then they have earned the one point badge of the Flyby. But if a person accrues one week of experience they earn a circle - solar symbol of the sun. Two circles indicates at least two weeks of experience, three circles indicates three weeks of experience. After one month of experience the person is promoted to the Lunar Badge.
