Hi
This variable was observed since a lot of decades, and mainly visualy.
It's so sad that now, only photometry is requested.
Is that really true ???

Hi Michel,
Visual observations are definitely needed - that is what I meant by "visual photometry". I changed the wording in the Alert Notice to "multi-color photometry and visual observations" so it would be more clear that visual observations are included.
Good observing,
Elizabeth
