The OPS team at NOAA and CNES applied immediately necessary procedures and the satellite is currently in a safe and stable Sun-pointing configuration. First investigations show that Gyrometer 1 was blocked, triggering the reconfiguration to SHM. The gyros temperature increase during the period where the Beta angle is high remains a concern. All other equipment is OK at the time of the reconfiguration. The period concerning the high temperature of the gyro will continue until October 3, so SHM recovery (NOMINAL MODE) is not expected before this date and likely not before the next YAW Fix period, which starts October 12.
