Pulsating object in the eastern sky

    Hey there I live in Toronto Canada and I have been seeing an odd pulsating light in the eastern sky. It seems to be pulsing at a regular rate and with colours ranging from red, orange, blue, and green. I have no idea what this object is but it certainly doesn't seem like a normal star. It seems to be moving with the backdrop of space but it's very peculiar. Can anyone help me?

    Thanks

    I just heard that from someone today! How cool is that... I have never known it to twinkle with such brilliant colours. It's must be the time of the year and possibly the effect of a colder denser atmosphere in the winter. Thanks for the reply.

    If it's showing colours then it wouldn't be Venus, only stars twinkle like that, due to them being a point source of light (because of their enormous distance from us).
    The planets have a reasonable angular size so any refraction through the atmosphere is averaged out and they don't twinkle (especially Venus). :)

    It probably is Sirius as it is quite spectacular in the south east after it rises around 19:30.
