HeI6678 observations in delta Sco
Posted: Tue Aug 26, 2014 3:21 pm
Dear colleagues,
almost at the end of the visibility (at least in Europe) here a conclusion of He6678 observations mainly of members of the ARAS group (and some others).
The V/R measurements of ten cycles led to a period of 550 (+/-) 2 days. Compare the result published in Be Star Newsletter: 40-2012 with 541 (+/-) 15 days of 5 cycles.
Any comments are welcome!
