I'll also send an email to the Ops Chiefs to let them know what happened. > >>Due to a MAP emergency, MGS support was transferred to DSS-65. > >>As far as the presence of some signal, the reported SNR (that is > >>relative to the expected value) appears to be the noise level. > > What is a MAP emergency?

Sometimes when the station declares an antenna red and switch to another antenna, the original antenna keeps tracking and we can sometimes continue to get data. However, this time the antenna was tracking another spacecraft, so it's surprising that you can see a signal.
