   I have relayed your new finding to the MISAO team.  However, the MISAO
team reports that Stephenson 141 was constant (within their observational
errors) for six months.  It is quite unusual for a Mira-star.  This may
suggest that the object has changed its pulsation characteristics.
Further observations are clearly needed.

   Now that 2MASS catalog is available, we can easily confirm both stars
as being bright infrared sources.
