Description:
We identified 240 accessible circumstellar shells with water and/or
SiO masers, and used the Arecibo and Nancay radio telescopes to search
for mainline OH emission from them. Our targets are often Mira
variables without previously known mainline masers. This search
results in 89 detections, of which 77 are new.
