Dear Vello Tabur and VSNET colleagues,

I am Seiichi Yoshida working on the MISAO Project.

Vello, congratulations on your discovery of new variable stars! I
visited your web page. I believe some of them must be real new
variable stars.

Yes, there are dozens of thousands of new variable stars discovered
recently in addition to the catalogs you have checked. As Fraser
kindly introduced, I have a database of many variable stars including
undesignated recent ones. The catalogs registered in the database are:
  http://vsnet.aerith.net/misao/pixy/catalog.html

I could not find the list of R.A. and Decl. of your new variable stars
on your web page. If it is available, I can check them with 1300
thousand objects in my database and the GSC, USNO-A2.0, Tycho data.

In general, including the MISAO Project, the special (not authorized
by GCVS, IAU, etc.) names are assigned to the new variable stars by
the discoverers. Vello, would you please assign the names for your
stars and issue a list of names, R.A. and Decl., magnitude range, and
so on? If the list is released, we can register it to the database and
make follow-up observations.

As Fraser pointed out, most of the MISAO images are of the Northern
Hemisphere right now. But southern images are also welcome!

Please assign the special name even if your star is identified with
GSC, USNO-A2.0, Tycho, IRAS, MSX5C, etc. because those names do not
express that the star is variable. In general, we do not assign a
special name when another special name has been already assigned as a
variable star. But it depends on the policy of discoverers or
projects.

Best regards,
