Omicron Aquilae (ο Aql, ο Aquilae) is the

mas,[1] which is equivalent to a physical distance of 62.6 light-years (19.2 parsecs
) from Earth.

The primary component, Omicron Aquilae A, is an

F-type star
.

In 1998, Omicron Aquilae was one of nine stars identified as experiencing a superflare. The first flare observed from Omicron Aquilae was in 1979, with a magnitude increase of 0.07 and a duration of less than five days. The second occurred in 1980, with a magnitude change of 0.09 and a duration of fifteen days. The energy released during the second flare is estimated as 9 × 1037 erg.[10]

There is a magnitude 12.67

optical companion that appears near the primary only through a chance alignment.[3]
