It's that time of year again...
Looking at the availability of AAVSO sequences (as opposed to those I created, accurate to 0.1m) it's clear that there is a 'seasonal gap'. Large numbers of stars in Southern Oph and Sco have no AAVSO sequences, for instance - and this area is a hotbed of star formation.
One obvious reason, other than the seasonal one, is that this area of sky is teeming with nebular material (often dark nebulae) which not only make it difficult to draw up workable sequences but also play havoc with the various waveband magnitudes because of the SEDs of affected potential comparison stars.
So... can our valiant Chart Team rise to the challenge?
