This time amavasai and "aipasi" vishu punyakalam are coinciding on the same day i.e. Sat, 17th oct 2009. Those who perform pithru tharpanam have a doubt as to whether only one tharpanam is to be performed or both. If both, which one is to be performed first - whether amavasai or vishu punyakalam. A suitable claification on this point will be very useful for the community.
