All times given in these predictions are in Universal Time. Predictions included both disappearance and reappearance times, although depending on the phase of the moon, one or the other may not be possible to observe at the instant of the event. When Moon % is "+" (waxing), the star will disappear on the dark side, and reappearance is on the bright side; when the Moon % is "-" (waning), the star will reappear on the dark side, and disappearance on the bright side. Observing disappearances and reappearance of stars on the bright side are difficult, and accuracies in timing these events are not reliable.If there are favorable graze limits, those will be posted ahead of time on the main IOTA webpage under the TIME CRITICAL section. All predictions and charts were generated using Occult v4.0.1 .
If there are no predications with the accompanying map of coverage, it is because it is either a daytime event, or in sparsely located regions where cities in the Occult database do not exist
