Description: NGC 2403 was difficult to see because of bright background sky. Only a core and the brightest parts were visible with averted vision. Supernova 2004dj (arrow) was the reason why I observed this galaxy. SN 2004dj was 11th mag and lies 2,5' east from the core. It was easy to identify from a CDD-picture.
