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 would like to contribute to AAVSO NEWS FLASH, please send
observations of unusual variable star activity to:
observations@aavso.org
Please include the words NEWS FLASH in the subject line of your message.
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.

We look forward to including your observations in future editions
of AAVSO NEWS FLASH!
