There’s still time to submit observing bids for NASA’s IRTF (infraRed Telescope Facility). The window for the late-2026 semester (2026B) opened on March 1… and closes April 1, 5pm Hawaii Standard Time. As I’ve mentioned, IRTF is one of the world’s top observatories for asteroid follow-up. Viewing in the infrared provides a breadth that visible light simply does not. Meanwhile, IRTF still has instruments that cover the visible, just to be sure:

“Proposals can be submitted to utilize a range of instruments spanning 0.4um to 25um, providing a range of spectroscopic modes with low resolution of 50 to high resolution of 85,000, and imaging modes with broad and narrow band filters. IRTF supports many planetary science programs covering all kinds of Solar System bodies, investigating the atmospheres of giant planets, characterizing small bodies and much more.”
Good luck all!
