GONG/Udaipur magnetograms

 On Jan 9 and 11 2026, site monitoring reveled several so called "blank magnetograms" in GONG at Udaipur observations. Their appearance was traced back to some issues with the workstations' precision timing board drivers, although the exact root cause is still under investigation. The affected data were removed and the higher level data products (synoptic maps) would be reprocessed. No significant impact on ZeroPoint operations, the chirpfit or network-merged Sunfit was detected.
