New Haseda variable (HadV46)

   Katsumi Haseda (Aichi, Japan) reports the discovery of a new variable
star (HadV46).

   Although the light variation is not inconsitent with a Mira-type variable,
the examination by Haseda of the RealSky image confirms the identification
with

= USNO0750.13650086 183404.041 -144500.23 (2000.0) 14.4 15.5

   , which is not red as expected from the light variation.  More detailed
observation (multicolor photometry and possibly spectrocopy) would be
desired to clarify the nature of the object.  The object is bright now.

   There is an IRAS source an arcmin away,

183401.4 -144534 (2000.0) IRAS18311-1447 0.596 1.371L 7.393L 104.700L -1%

   but is more likely identified with a red star

USNO0750.13647965 183402.251 -144533.69 (2000.0) 11.6 16.7
