OccultWatcher is a Windows program that helps astronomical occultation observers to stay tuned with the incoming events by tracking the asteroidal occultation predictions published and regularly updated in various sources called feeds. OccultWatcher searches the feeds you have subscribed for, for events that match your specified distance, star magnitude, event duration and other filter criterias. It allows you to announce your intentions to observe an event to all other observers around the world and helps the cooridnation in a global scale. At the time of the release of verion 3.2 there are more than 400 registered accounts (of people that announce their observing intentions) and more than 1500 known installations. The account registration and usage as well as the OccultWatcher software are absolutely free.
The following prediction feeds are currently available for subscription:
With the release of version 3.2 there is one new feed called "Planned Observations". This feed contains all events that someone has already announced a station for. This way even if you are not particularly interested in the events of an existing feed, if there is an event that comes close to you and matches your filter criterias and if there is at least one announced station for it, OW will show it as "Planned Observation". This way events that are going to be attempted by an observer could get more observations.
With its enhanced alerts and reminders OccultWatcher can be also very helpful for tracking your personal asteroidal occultation predictions generated using prediction software such as Occult and LinOccult. It provides extra and very detailed information for all predictions including parameters of the star and asteroid, information about double asteroids, historical observations data and others. The software comes with a function to draw star charts using the free planetarium program C2A developed by Philippe Devechere in France and which supports the star catalogues: Hypparcos, Tycho2, UCAC2, NOMAD. OccultWatcher also provides ability to be extended by your own Add-ins written using Microsoft.NET
If you are new to asteroidal occultations here are some online resources you would find most useful:
Software Requirements for running OccultWatcher:
Hardware Requirements: Anything that can run the required software.
Internet Connection Requirements: In other to receive information about the predictions from the online feeds you need an internet connection. There is no particular requirement for the speed of your connection, but as a general rule OccultWatcher will do well so long as your connection allows you to view maps using GoogleMaps without too much delays.
