Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 30 September 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 January 2029.

Abstract

This program implements a near-Infrared Wavefront sensor (‘IWA) for the Keck II telescope adaptive optics (AO) system. AO systems correct atmospheric blurring, allowing ground-based telescopes to achieve images as sharp as telescopes in space. A bright guide star is needed to measure the atmospheric errors, and doing so in the infrared enables lower-mass and dust-obscured stars to be used. ‘IWA enables a broad range…
