The observation made by Michel Verdenet ( Sgrnova2001-3 20010905.814 6.0::) was a prediscovery sighting. Michel serachs the variables and her fields by progression from star to star and utilised the alignement delta-gamme Sgr in order to reach V1017 Sgr. He noticed an orangy star lightly weaker (6.0::?) than the nearby mv 5.6 star. He was surprised but observed V1017 Sgr and then the nova 2001-2 ... and did dot verify the chart. The meteo is changeable, the moon disturbed and other variables were scheduled. Just his luck ! E. Schweitzer - AFOEV sorry for my "dictionnary english"
