The MIGHTI temperature product (L2.3) has been updated to version 6 (v06) and is currently available for the full mission on the ICON FTP site and at SPDF. 

With this version update, the MIGHTI-A and MIGHTI-B temperature data are both more rigorously tested to ensure continuity across the solar terminator. Also, the top of the daytime MIGHTI-A temperature profiles is now 135 km, up from 127 km in previous versions. Links to the data products are provided here:

ICON FTP Temperature V06 Documentation

It’s about a year until ICON launches, and all teams—science, instruments, mission operations and modeling teams—are moving forward with laser focus. There is little time to rest when so much goes into making a NASA satellite ready for launch in June 2017.  Systems need to be tested to ensure they can download and process the data that ICON will be generating nearly continuously, orbit after orbit, in Earth’s upper atmosphere. Current data processing testing is making use of the data that the flight instruments are already producing as they undergo ground testing—it's a great way to see how everything's flowing through the data pipeline.  In fact, the mission and instrument operations teams worked together recently to perform a “day in the life” test with the instruments, where they ran them through a 24 hour long sequence of commands, to simulate what they will do over a full day's worth of orbits.
