Some delay caused by inconsistent target coordinates provided by PI for the IGR J18410-0535 TOO. This has now been resolved. Eng: Prop line temperature limit violation (low) again seen. No immediate concern but investigation continues. FOT considering whether to change the yellow limits. Radiation: Solar activity is very low at this time. All radiation indicators are very low. Solar Activity Forecast: Solar activity is expected to be very low. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled, with isolated active conditions possible all three days from the effects of a recurrent high speed solar wind stream.
