NOTICE

Over the past 20 years, I have generated and posted bright star occultations. Beginning with the 2017 occultations, only those of 3rd magnitude and brighter will be listed.

In recent discussions, the value of total occultation have come into play. "In this day of LOLA lunar profiles and space-based astrometry (Hipparcos, & now Gaia), there is little scientific value in timing occultations now. Observations of grazes, especially video, provide enough accuracy to "push the envelope" on current knowledge, but the main value is to discover and resolve close double stars that can't be separated directly" - David Dunham (former president of the International Occultation Timing Association). Focus of IOTA has also shifted to asteroidal occultation events, and those predictions can be found at Steve Preston's web site and regional information found at Derek Breit's website.

I encourage those who are interested in observing and reporting these events, to download the Occult software (link given below), and generate predictions for their particular location/site. David Herald, author of the software states that he discovers a new binary star in about every 100 observations or so. The software will give you the opportunity to observe much fainter stars than what has previously been listed, making it possible for you to discover your own binary star systems.

I appreciate all the comments and help I have been given in maintaining this portion of the website.

2016 BRIGHT STAR OCCULTATIONS


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 (DD), and reappearance is on the bright side (RB); when the Moon % is "-" (waning), the star will reappear on the dark side (RD), and disappearance on the bright side (DB). Observing disappearances and reappearance of stars on the bright side are difficult, and accuracies in timing these events are not reliable.

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

The world map is a Mercator projection showing the basic circumstances of an occultation:

  • Cyan - the curves of Occultation D or R at moonrise or moonset
  • White continuous line - the northern and southern occultation limits (graze paths), with the event occurring in nighttime
  • Blue continuous line - occultation limits, event in twilight
  • Red dotted line - occultation limits, event in daylight

Where a line represent a feature of the event is located in the polar regions, remember that the Mercator projection gives rise to serious distortions in polar regions.

Events which occur during daylight or near full or new moon are not shown in the predictions

Predictions and world path maps were generated using Occult v4.1.6.1

You can generate predictions for your own site coordinates, plus many more fainter occultations, by downloading the free Occult software for your own use. After installation, there is a tutorial in the program which will guide you through the fundamental operations.

Note: Cities will be prefixed with their 2 letter country code. Those for the United States will also include the 2 letter state code after the city. For a complete listing of the 2 letter country codes used in the predictions please download this PDF file for reference.
