The comparison star for the campaign target HD 15407A has been changed. The 96 (HD 15407B) has been dropped because its published magnitude is highly questionable. The 95 and 102 in the field are to be used instead. Photometry reduced using the 96 (or anything other than the 95/102) needs to be re-reduced and old data in the AID replaced. Please see AAVSO Special Notice #373 for details.
Many thanks, and good observing - Elizabeth Waagen, AAVSO HQ
