Yellow text is a warning, red text is an error.
This is informing you that your mount is currently in the zone near the meridian that you have defined as “only take exposures.”
From the Wiki:
Only Exposure Action Before Meridian Crossing : During a sequence Voyager can slew the mount (do a goto) for various purposes, such as to find a focus star or to re-target after a guiding error. If non-zero, this setting prevents Voyager from performing a slew (goto operation) of the mount for this number of minutes before the target crosses the meridian. Normal operation will continue, exposures and guiding will be done; but if Voyager needs to slew the mount for focusing or re-targeting, the slew will not happen and the sequence will continue to run. If an emergency goto for re-alignment is needed, Voyager puts the Sequence in standby until the mount has passed the meridian by the number of minutes designated in “Do Flip After Mount Passing Meridian By.” At that time, Voyager will perform a goto to do the meridian flip and resume the sequence. This is done to avoid the critical zone around meridian flip time, and wait until the mount is at a position where a goto is sure to not trigger the meridian flip.
