the sun: cf. F. h['e]liaque.] (Astron.)
Emerging from the light of the sun, or passing into it;
rising or setting at the same, or nearly the same, time as
the sun. --Sir T. Browne.
[1913 Webster]
Note: The heliacal rising of a star is when, after being in
conjunction with the sun, and invisible, it emerges
from the light so as to be visible in the morning
before sunrising. On the contrary, the heliacal setting
of a star is when the sun approaches conjunction so
near as to render the star invisible.
