AQUA IIRV Anomaly Data Loss

On October 5th 2024 (2024/279), significant data losses occurred for MODIS AQUA (C61) due to an ongoing Improved Inter-Range Vectors (IIRV) anomaly during the last few days. Increased solar activity in the past few days has interfered with the ground stations' spacecraft tracking causing data loss during downlinks. The ground stations are working on adapting to the ongoing anomaly.
