SMA fringe test with Nāmakanui a success

The JCMT had a successful fringe test yesterday with the SMA using the new instrument Nāmakanui; on loan at JCMT from ASIAA. The JCMT got fringes without problems which is really excellent news. This is good progress with an East Asian VLBI and Event Horizon Telescope run schedules in 2020. JCMT staff also confirmed the basic orientation of the lambda/4 plate – used for polarization measurements. Poor weather does mean there is still more to do, but congratulations to all involved. Staff are now looking to further testing of Nāmakanui at the EHT test run in January and for data taking during the March/April EHT campaign.
