Hello all, here is an uncomplete Map
 of NPC from my obs on 14 & 18 March, in comparison with
 historic draw by J.Beish.I hope I 'll have the chance to
 complete it.
 It seems visualy  that NPC has shrunk more
 thanthe  historical average suggest (more than 80deg)
 but of course this needs extensive measurements in many
 images end not just a fast visual estimation.
