Surya is an open‑source, AI‑based foundation model for heliophysics developed collaboratively by NASA (via the IMPACT AI team) and IBM. Named after the Sanskrit word for “sun,” Surya is trained on nine years of high‑resolution solar imagery from NASA’s Solar Dynamics Observatory (SDO). It is designed to forecast solar phenomena—such as flares, solar wind, irradiance, and active region behavior—by predicting future solar images with a sophisticated long–short vision transformer architecture,...

V1.4 fix issues with PHP 7.3 The A-GM project is aimed for providing a long-term continuous measurement of the radioactivity level. It includes an open-source Web application (A-GM Manager) running on a SOHO server (e.g. NAS from QNAP for Small Office Home Office servers) connected to a Geiger-Muller radioactivity counter device such as C-GM Counters (https://sourceforge.net/p/c-gm-counter) or compatible counters from GQ Electronics LLC. Other compatible or DIY Geiger-Muller counters...
