HR Car
P. Williams reported that the SDOR star HR Car has been unsteady between
7.4-7.8mag since 2002 January (vsnet-campaign-sdor
14). B. Monard commented that the object is a tricky star to estimate,
and it is in an active state over two years (vsnet-campaign-sdor
15). S. Otero noticed that the long brightening of HR Car deserves more
attention. He found out that it has been brightening continuously since
1967 to the present, as if it was in an eta Carinae-like event of dust and
gas dispersion. The brightening became steeper since the very end of 1990
when mean magnitude rose from 8.0 - 8.3 to 7.5. By the end of August 2001,
the star reached a record-breaking maximum of V=6.7 and the variations mentioned
above were in the range 6.7 - 7.2 at that time (vsnet-campaign-sdor
19).
