REX is now getting in position for the occultation measurements. It will remain in this configuration until then. The occultation of Pluto with the Sun/Earth will occur in about 30 min starting around 8:45 ET.

Bring home the data baby!
Nope, it is not sending data. It is setting up to receive the DSN signals from Earth to begin the occultation measurements.

Technical explanation of the radio occultation experiment: https://books.google.it/books?id=oZfpYIUKDrUC&pg=PA217&lpg=PA217&dq=earth+occultation+new+horizons+radio&source=bl&ots=xu5-CeeM4t&sig=ymDS-ldHIE1KQzsQS_Sl1GD45VQ&hl=it&sa=X&ved=0CD0Q6AEwA2oVChMIq-3Emc7axgIVRB0-Ch2s1wVa#v=onepage&q=earth%20occultation%20new%20horizons%20radio&f=false

A powerful signal sent from Goldstone and Canberra's DSN stations 4 hours ago is now being recieved by NH and it will check how it's distorted by Pluto and its atmosphere.

Wish NH could burp a brief acknowledgement of its status at this point, so we know it's still alive and on-script.

Very in-depth response from Alan Stern about RTGs and how long it'll last on New Horizons (will run out of power by mid-2030s)

According to the timeline, linked early in the thread,  I think it does.

Won't be received until around 01:00 UTC tomorrow, though.

Occultation of sun begins. First ever human-made object to be in pluto's shadow. Sunrise soon. Then another sunset and sunrise from charon. That occultation will be the last time a shadow ever falls on New Horizons.
