1-Cas (Star)
R/B-band color composite image from the Second Digitized Sky Survey (DSS2), measuring 30 arcminutes across.
From South El Monte , 1-Cas is visible in both the dusk and dawn skies. In the evening, it will become visible at around 18:42 (PST), 28° above your north-western horizon, as dusk fades to darkness. It will then sink towards the horizon, becoming tricky to observe after 20:04 when it dips 19° above your north-western horizon. At 05:23, it will return to an altitude of 19° above your north-eastern horizon, and reach an altitude of 19° before fading from view as dawn breaks at around 05:26.
