[vsnet-alert 4411] Re: Hen1341 bright state continues



Hi Taichi and readers,
 
using the Tycho2 magnitudes I have been able to recalibrate the Hen 3-1341 observations. They show clearly that the outburst started in 1998 and the bright optical state still continues up to now. Unfortunately I did not observe this symbiotic system in 1999.

Hen1341 bright state continues

  The symbiotic variable Hen3-1341, which is reported to have gone an outburst
in 1999, is observed still bright.
