We are glad to announce the first Phasing@Home event, an online meeting devoted to presenting ARCIMBOLDO, Phaser, SHELX and XDS software and their use in challenging phasing cases.

The event will be held online on the 13th and 14th of July. Talks will be streamed via Zoom and interaction among speakers and participants will be through a Discord server.
