The brightest recurrent nova, T CrB, has been reported to be showing 
some activity as indicated by the following recent observations:

This recurrent nova has an orbital period of 227.59 days (Warner, B.
1995, Cataclysmic Variable Stars, Cambridge University Press, Cambridge)
that can be seen in the light curve as small amplitude periodic modulations.  
The recent activity may be due to this and deserves the attention of 
our observers.

The last major outburst of this recurrent nova was in 1946 when it 
reached magnitude 2.0. 


Astronomers at the University of Colorado and also Louisiana State 
University are scheduled to observe the interesting R CrB star, V348 Sgr 
with the Hubble Space Telescope on April 28th at 22:00 UT.  They hope to 
observe this star at its maximum.  

V348 Sgr faded from maximum between April 15th and April 20th and is now 
slowly recovering, with oscillations, from this short duration fading as 
indicated by the following observations:

Please keep a close eye on V348 Sgr and keep us informed of its 
behavior.  If it starts to fade again, from now until April 29, 
let us know by phone/e-mail/fax immediately.

AAVSO NEWS FLASH is a new electronic publication of the AAVSO intended
to provide observers with timely information on unusual variable star
activity.  The basis of the data in this publication will be the
observations reported to AAVSO Headquarters.

The AAVSO NEWS FLASH will not replace the AAVSO Alert Notice.  It will
be more frequent and shorter.

If you are affiliated with a variable star organization besides the
AAVSO, and you wish that group to be indicated with the observations
that you provide, please give the specific name of the organization or
group and its abbreviation.
