The bright Be star
Canis Majoris
is in a bright and long outburst that started at the end of March
2001. By that time the star rose slowly and steadily from 4.1,
reaching 3.8 in early June when it got very low to be observed. Now it
is at 3.7, half a magnitude brighter than in its quiescence state. The
lightcurve of this outburst mimics the one caught by Hipparcos in
1992. It would be important to take spectra of this star now that is
at maximum and to compare them with the visual behaviour.
(28) CMa is located
at: RA = 07h 14m 48.65s,
Dec = -26º 46' 21.6" (2000.0). The range given in
the GCVS is 3.60 - 4.18 in V.
