XX Ophiuchi in deep minimum after 37 years.
SOBOTKA P.
Abstract (from CDS):
XX Ophiuchi is a unique object, which is very difficult to classify. This star only slowly varied around the maximum magnitude (V approx 9 mag) during the past 37 years. In March 2004, the brightness started to fade by 0.2 mag per month. I stress the urgent need of the spectroscopic observations during this minimum.
