Skywatcher Alan Cumming is calling on amateur astronomers to join the American Association of Variable Star Observers (AAVSO) and record information on neglected stars:
[AAVSO] have recently published a prioritized list of Stars In Need Of Observation, called ‘Bulletin 71’. The AAVSO is perhaps the most direct way that amateurs like me can co-operate with their professional counterparts, and these ‘Stars In Need’ are a group of objects that are in the middle of an interesting and complicated part of their evolution: They are the red and slowly pulsating Long Period Variable stars (LPVs).The manual's arcane cover (right) is reason enough to sign up right now.
