I'm on my way to look up DKIST, but after SOHO, it's hard to imagine needing ground based solar observatories. Of course, SOHO will eventually come to end of mission, so we definitely need other observatories. It's just the SOHO imagery is stellar.

You’re a little out of date! SoHO is largely shut down, has been for a decade now. Its tent pole instruments were replaced by SDO in 2010. (https://sdo.gsfc.nasa.gov/mission/)

Both of these are NASA, not NSF, observatories. They were (SoHO) and are (SDO) amazing resources that have advanced the whole area of heliophysics.

DKIST (NSF) has a 4m aperture. Unbelievable for a solar telescope, and of course, impossible to fly under reasonable NASA heliophysics budgets.
