    Hi all,
    Just wondering if anybody can tell me what is the really bright star in the sky that I've been really noticing lately in the South-East sky. I notice it from my window most of the nite when the sky is clear and it seems to stay in same position, unlike moon it doesn't move at all and its way brighter than anything else
    i am in Lucan area

    Thanks in advance

    Nothing can remain still in the SE sky, the Earth’s rotation means that it will gradually rise until it reaches maximum altitude (for that night) when due S and then it will descend into the SW and set.

    Sirius is visible in the SE early in the evening nowadays but it doesn’t stay still. Are you seeing Mars soon after sunset? It’s currently due S at about 7 p.m. The only star that stays in the same place in the sky is Polaris, the (north) pole star. But that’s due north, always.

    As the above poster said, it's likely Mars or Sirius. Mars is bright with a slightly orange hue and does not twinkle but it moves across the sky quicker than stars. Sirius is bright and it's twinkle can be intense, almost flashing between red, white, and blue. If you know how to identify the constellation Orion, Sirius is always close to the bottom left star (Saiph) (is that what you mean by it stays in the same position unlike the moon?).

    Picture taken at 19:07 this bright star can be seen already since there’s still light in the sky

    Sirius probably. It's the brightest star in the night sky.

    Impossible to tell from a grainy photo and nothing else in the photo to use for a sense of positioning, but if it’s a bright star in the south early in the evening then it’s almost certainly Sirius. Right now at half ten it’s about 218deg SW. It’s a clear night and Orion is clearly visible (in Cork at least) so if you can identify Orion you should be able to see Sirius to the bottom left of it.

    Try downloading SkyView or Night Sky on your phone to help you identify it.
