We present space-based photometry of the transiting exoplanetary system HD 209458 obtained by the MOST (\textit{Microvariablity and Oscillations of STars}) satellite. MOST has observed the system with 14 day and 44 day observing runs separated by one year. We will report on observations and analysis for secondary eclipse detection in this system. We present reduced photometry and its implications for the depth of the eclipse which in turn is translated into an optical albedo (or an albedo upper limit) of the exoplanet. We discuss the implications of the albedo for constraining planet atmosphere and cloud models.
