Alert Notice 859: Photometry and spectroscopy requested for bright binaries being observed with CHARA - Revised

Note: The Alert Notice text below has been revised from the original version issued April 18, 2024.  - Elizabeth O. Waagen, April 19, 2024

Observers are also reminded that it is essential to use the comparison and check stars indicated for the photometry target. If they are too far apart to fit into the same field of view as the target, use PEP-style observing, that is, alternate images of variable, comp, and check.
