GONG station at Learmonth is back to operation

On 11 October 2025, GONG station at Learmonth (Australia) stopped recording Doppler velocities and magnetic field. H-alpha observations were not affected. The remote diagnostics identified that the camera trigger cable was broken. The cable was repaired with the help of site support personnel and reconnected. Data acquisition was restored on 17 October and a calibration set passed. GONG/LE is now back to full operation. The most recent magnetogram is shown on the right.
