I walked outside about 45 minutes after sunset, and Delta stood out almost as boldly as Antares. I know it is a Gamma Cas type variable and has had some flareups in recent years, but I had not particularly noticed it lately. Might this be a new flareup?

I just had a look at it and - yes it is looking quite bright. Also, looking at the AAVSO data it seems to be near the brighter end of its normal range.

An excellent recent article is at AAVSO Delta Scorpii: the birth of a Be star (http://www.aavso.org/vsots_delsco). It links to the observing campaign of the next periastron passage in 2011 (http://www.uncg.edu/~a_mirosh/Delta_Sco/).

Sky and Telescope had an article (http://www.skyandtelescope.com/news/3305526.html) about the 2004 flareup.
