## What is OW Mobile 2?

OW Mobile is the official companion app for Occult Watcher Cloud (OWC) — the planning and reporting platform developed by Hristo Pavlov and used by amateur and professional astronomers to observe asteroid occultations, the brief moments when an asteroid passes in front of a star and its shadow sweeps across the Earth.

Sign in with your existing Occult Watcher account to:

• Browse your upcoming occultation events, with remaining time, station count, star magnitude and colour, and expected magnitude drop at a glance
• See a full event detail view for each occultation, including a shadow-path diagram showing the predicted shadow track, uncertainty zones, and every registered observing station
• Search for new events to observe by date and by your own saved filters, with sun altitude, moon phase and distance, and a live cloud-cover, wind and temperature forecast for the night
• Register yourself as an observing station directly from the app, and see other observers already registered for the same event
• Submit your observation report — outcome, duration and comments — straight from your phone after the event
• Get local reminders ahead of events you're registered for, so you don't miss the window
• Customize units and formats to match how you like to work: temperature (°C/°F), azimuth, date/time (local or UT), star coordinates (apparent or J2000), and location format (DMS or decimal)

OW Mobile keeps your events, stations and reports in sync with the desktop and web versions of Occult Watcher — plan on your phone, observe in the field, and report the moment you're done.

An Occult Watcher Cloud account is required. Create one for free at cloud.occultwatcher.net
