[vsnet-newvar 930] LMC V2434 - UCAC1 position

[crawl@zoom.co.uk]

LMC V2434 is also 1UCAC 1390649 :

RA:  5h24m01.61s dec: -71d 09' 34.5"

(Mean epoch: 1998.772 [of 2 observations]; equinox J2000)

Proper motion in RA: 11.0 +/- 10.9 milliarcseconds/year
Proper motion in dec: 71.3 +/- 10.9 milliarcseconds/year

UCAC-CCD-RED magnitude 12.42

Note that this position is very close to that given by 2MASS, with both
being about an arcsec north of the GSC one.  The version of GSC used wasn't
quoted, but if the 1987.064 position is taken as the epoch (as per GSC-ACT
I believe) the above proper motion in dec gives about 14 years for an
arcsec to be traversed, whereas the 1998 epochs of the 2MASS and UCAC1
positions are about 11.5 years following the GSC one, which is around the
right area.

Also: GSC2 S0101012106  RA 05h024m01.55s Dec -71d09'34.7"  mean epoch
1996.770508  Vmag 12.53

and: DCMC J052401.65-710934.8
