Alert Notice 660: Targets modified for LPV Maser campaign
Abstract:
Further to AAVSO Alert Notice 645, Michael Stroh informs that two of the VLA targets on his list of 19 long period variables for his SiO maser study have been removed and two others added.
Justification:
We believe that the strengths of the SiO maser lines we observe at 43 GHz in the radio are correlated with the phase of the stars in our sample and may allow us to probe the density in the stellar envelopes.
