At around 3:30 UTC I set both upper and lower ring heaters on ETMY to 0.75W, this reverts us to the settings we had in early and mid July, and the first part of ER9. This was changed to 0.54 July 23rd.
It also means that now the two arms have the same ring heater settings:
ITM: 0.5 Watts total
ETM 1.5 Watts total
