MISAO Project Announce Mail (April 16, 2000)

CCD images are welcome.

Hello. I am Seiichi Yoshida working on the MISAO project.

The MISAO Project Home Page is renewed in January and moved to the
following new URL in March.

  http://www.aerith.net/misao/

The MISAO Project aims to discover new celestial objects like variable 
stars as a result of collaboration, by examining CCD images offered by
many people using the PIXY system. For that purpose, your CCD images
are welcome. The new MISAO Project web pages describe how to offer CCD 
images to the project, the copyright of the offered images, and the
rules to settle the discoverers of new objects discovered from the
offered images. 

The CCD images saved in FITS, MTF or SBIG format are welcome in
principle. The image data such as approximate position in the sky,
accurate date and time of exposure, used filters, etc., must be
recorded.

The offered images to the project are examined by the PIXY system and
new objects are searched. At the same time, the data of known objects
like variable stars are measured, too. In addition, the examined
images are stored in the MISAO Project database. When new images of
the same area are offered in the future, they will be checked to
search new objects. When an outburst or something happens, they are
checked for the past data.

On April 16, 2000, totally 8461 images are stored in the database
taken between 1997 May and 2000 March. From the images, 882 new
variable stars were discovered. And 46152 magnitude data of 4340
variable stars were measure, which were reported to VSNET (Variable
Star Network) and VSOLJ (Variable Star Observers' League in Japan)
by the observer code of the MISAO Project, "Mis".

The new variable stars discovered from the offered images are named as 
"MisV" with sequential number. The image contributors of the
conclusive images for the discovery are settled as discoverers of the
star, as well as the MISAO Project staff who really discover it on the 
images. The names of the discoverers are described in the web pages
and papers.

Very old images are also welcome to the project. Especially, old
images are as valuable as the recent images in case of variable stars.
If a bright star was found only on the old images and not found on the 
recent images, it may be a nova or something rare star. And this star
must not be discovered if the old images were not offered and
examined. When very old images are offered, compared with the recent
images already stored in the database, and new variable stars are
discovered, the MISAO Project considers the very old images as
conclusive ones for the discovery and the image contributor of the
very old images is prioritized. 

In the MISAO Project database, over 8000 images are stored. If you
are interested in the collaborated discovery, we will show you the
areas of the past images in the database. Please make a contact to
the image conductor, kenIchi Kadota (kenic-k@astroarts.co.jp).
By comparing with the past images, new objects can be discovered from
your images of one night.
