The micro Advanced Stellar Compass (µASC), an instrument onboard Juno that serves as an attitude reference for the Juno Magnetic Field investigation, provides accurate bias free attitude information continuously throughout the mission. These optical sensors are optimized for low-light scenarios, which enables detection of stars and objects as faint as 7-8Mv.

The highly elliptical Juno orbit configuration, in combination with the 13° off pointing of the star tracker cameras from the Juno spin axis in anti-sun direction, enables the Jovian night side to enter the field of regard. For certain Perijoves, the Galilean satellites have provided ambient illumination of the Jovian Atmosphere, enabling the star tracker cameras to detect the upper haze layer of the atmosphere. These findings will be presented together with the detected energies within the sensitivity range of the observing star tracker camera.
