Receive alerts of Gravitational Wave Events from the LIGO/Virgo Collaboration (LVC) on your iPhone.

This is an app for both the LIGO/Virgo Community and the general public. It provides low latency alerts using the Open Public Alerts currently being deployed by the Gamma-ray Coordinates Network (GCN) through GCN/LVC Notices (https://www.ligo.org/scientists/GWEMalerts.php). To receive alerts using the app just select the category of alerts you wish to receive - it's that simple!

The app will download all O3 events and counterparts as they are reported through a GCN Notice in addition to any related GCN Circulars. (As of this date there are no events from O3.) The app database is pre-populated with selected Notices and Circulars from all O1 and O2 events. The app retains Notices for one Mock Event reported through GCN for testing purposes. (For information on LIGO/Virgo Collaboration GCN Notices see: https://gcn.gsfc.nasa.gov/lvc.html.)

The app also has a public Message exchange bulletin board and some interesting Links. The Links provide information on Gravitational Waves and the LIGO and Virgo observatories.

What’s New

Version 1.5

Version 1.5 resets all subscriptions and asks to allow notifications more correctly.
Version 1.4 handles notification contents more efficiently. The full Event text is included in the notification. Database fetches are minimized following a notification. This will allow the full community to access Event information immediately upon receipt of a notification.
