I presume that Richard Huziak referred to the classical paper by
Schaefer, who studied past records of short-lived phenomena in Mira stars
and other objects. I vaguely remember these was a theoterical paper
that such phenomenon is possible, but I'm not sure.
We can now study thousands of Mira stars with ASAS-3 public data.
They are CCD-based, and we can directly see archival images (at least
for the older data). Would someone try to make a better statistic for
the claimed presence of short-lived phenomena in Mira stars?
