Witness Account

I see a bright star like object from our back yard every night for the last 3-4 weeks. It does not seem to move however, after almost 2 hours it starts moving slowly to the right & then disappears. There is no sound associated with this object and seems to be flashing slightly. I am not sure what it is but for sure it is not a star or an aircraft. Even with cloudy sky covering all the stars, this object is very bright & visible. I have taken a photo of this object & I can email it necessary.
