How bright is Asteroid 349 Dembowska (1892 T)?
The current visual magnitude of Asteroid 349 Dembowska (1892 T) is 11.55. Given its brightness, Asteroid 349 Dembowska (1892 T) should be visible with the help of a telescope havng an aperture of 4 inches (100mm) or more.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 349 Dembowska (1892 T), according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
