Iras 21204+4913

This is a probable FUOR wih a recorded outburst in 1948 that is currently in another; fading slightly from a visual max of ~11m in the latter part of last year. I have done a sequence down to 15.4mv, with the star very easy to find inside a bright equilateral in the region of M39. There is a link to an excellent paper in the current YSO newsletter.

… and we already have over 1000 obs of it too. The aTel is a definite confirmation that it is a FUOR from the telltale ‘double spectrum’
