What Wiyn Consortium Inc does
Mission
To advance astronomical research and education by constructing and operating the wiyn observatory for the purpose of allowing the scientists of the member parties to obtain observing time.
As stated on its FY2025 Form 990.
Program
On its FY2024 return the organization reported a significant change in how it conducts a program.
In april 2023, the wiyn board of directors voted to terminate all agreements related to the 0.9-meter telescope which has not been in operation since march 2020. The 0.9-meter telescope did not incur operating expenses in fy25. Expenses recognized related to the application of final rate adjustments from prior years.
Its own explanation, from Schedule O of that return (Part III, line 3).
Construction and operation of astronomical research facility - 3.5 meter telescope.

The program described on its FY2024 Form 990. Program spending in total: $3,960,976.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $27M to $25M (−9%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 51% · 2018 63% · 2019 60% · 2020 58% · 2021 59% · 2023 22%. Grants only. Government contracts and fees sit inside program revenue.
20% of WIYN CONSORTIUM INC’s revenue is contributions — about as donation-reliant as the typical peer (67% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 7 of the last 9 reported years ran a deficit.
