[Haakon Andresen]

Dear Everyone,

While there is no EO seminar this week, Felix Ryde has a visitor that will give a talk on the 9th (Friday),
that should be off interest to several of us.

The details are below.

Best,

Title: General Coordinates Network (GCN): NASA's Next Generation Alert System for Time-domain and Multimessenger Astronomy
Speaker: Vidushi Sharma, NASA/GSFC
Friday 9 June at 14:00
Room: A5:1003(AlbaNova Main Building)
Content: Gamma-ray Coordinates Network (GCN) is a collaborative platform operated by NASA to facilitate the sharing of alerts and quick communications regarding high-energy, transient, and multimessenger phenomena among the astronomy research community. Over the last 30 years, GCNhas enabled significant advances by disseminating observations, predictions, requests for follow-up observations, and observing plans. GCN distributes alerts between space and ground-based observatories, physics experiments, and thousands of astronomers worldwide. As new transient instruments spanning the electromagnetic spectrum and multimessenger facilities become available, coordinating efforts have become more vital and complex than ever. Introducing the General Coordinates Network (GCN), an updated version of GCN designed with modern, open-source, reliable, and secure alert distribution technologies, and deployed in the cloud. The new GCN is built on Apache Kafka, the same alert streaming technology that the Vera C. Rubin observatory uses. We will present the current status and design of the new GCN, the streaming of notices and circular alerts with Kafka, and a vision of its growth as a community resource in the future.
