HD 5980
Rapid fading of this object was detected from observations by A. Pearce
(vsnet-sdor 9).
The magnitude reached 11.4 on October 17. About this
fading, T. Kato forwarded a message from Dr. Koenigsberger in
[vsnet-campaign 532].
According to it, the fading phase correspond to the
orbital phases between 0.2 and 0.4 (P=19.266) which coincide with the
eclipse of Star A (the LBV/eruptor) by Star B (presumably the original WR
star), although a drop by 0.7mag does seem a LARGE drop for visual
magnitudes.
