Addressed mainly to those who are engaged in making charts for YSOs, this is a reminder that most of the stars in some spring-summer constellations will need accurate sequences. At the moment, we have charts from UCAC-3 with visual mags to 0.1m. Since all these stars are in the South (Sco, Oph...) you should be able to use accurate mags derived from ASAS. I know Sco and Oph aren't quite with us yet, but there are an awful lot of YSOs in Scorpius! I'll start on some of these myself, but it's a worthwhile project for us poor old Europeans who are snowed/frozen out!
