[vsnet-chat 1814] Eta Car (don't panic yet ;-)

["Fraser Farrell" <fraserf@dove.net.au>]

G'day all,

After receiving several private queries about the latest antics of 
Eta Car I've decided to reply collectively in vsnet-chat:

- tonight's visual magnitude (by me, 7x50 binoculars) is 5.1.

- my impression of Eta Car's colour in 7x50's is that it looks 
about the same as a naked-eye view of Alpha Sco.

- I will put together a recent lightcurve and place it on the Web 
when I have some spare time(!)

- I know of dozens of people who at least glance towards Eta Car every 
clear night.  We won't miss a "SN Eta Car" unless it's raining.

- the interesting spectral variations predicted by Daminelli et al 
for late 1997 (and subsequently observed) were imperceptible to visual 
observers.


I think that covers most of the questions?!  ;-)




cheers,
Fraser Farrell
