There is no consideration of auspicious (proper) or inauspicious (improper) time for chanting ... During the eclipse, a bonafide devotee does not perform rituals like taking bath in Ganga, etc., i.e., they do not perform any fruitive activity desiring for the result. Today, I am going to Mathura Mandala to take bath in Sri Radha Kunda.
Your ever well-wisher, Sri Siddhanta Saraswati
