<h3>8: Target</h3> <h3>8: LST - Local Sidereal Time</h3>
The LST field displays the local sidereal time at the specified location (5&6) and Solar time (7).
<h3>9: Solar Flux</h3>
The Canadian Solar Radio Monitoring Program measures the Solar flux at 10.7cm three times a day, and is reported in Solar Flux Units (sfu), where 1 SFU equals 10,000 Jansky or 10^-22 Wm^-2Hz-1.
The Solar flux field displays this flux value, using units that can be set in the settings dialog. The field is updated every 24 hours.

<h3>9: Right Ascension</h3> <h3>11: Right Ascension</h3>
When target is set to Custom, you can specify the right ascension in hours of the target object. This can be specified as a decimal (E.g. 12.23, from 0 to 24) or in hours, minutes and seconds (E.g. 12h05m10.2s or 12 05 10.2). Whether the epoch is J2000 or JNOW can be set in the Star Tracker Settings dialog. When target is set to Custom, you can specify the right ascension in hours of the target object.

<h3>10: Declination</h3> <h3>12: Declination</h3>
When target is set to Custom, you can specify the declination in degrees of the target object. This can be specified as a decimal (E.g. 34.6, from -90.0 to 90.0) or in degrees, minutes and seconds (E.g. 34d12m5.6s, 34d12'5.6" 34 12 5.6).
