                          EK Lac = NSV 14025


  During my work on PICA project (Precise Identification and Coordinate 
Adjustment of about 7000 variables) I have found that EK Lac is identical with 
NSV 14025.

  EK Lac = SVS 1114 was discovered by Kurochkin in 1949 (Kukarkin, 1952).
Kukarkin (1952) has investigated this star and gave the light elements and finding
chart for this eclipsing binary. The star has received its final designation in 1952
(Kukarkin et al., 1952). From that time only times of three individual minima have
been secured.
  NSV 14025 = Brun 29 was discovered by Brun (1964), giving also the finding
chart. No final designation was accepted for this star and it was included into New
Catalogue of Suspected Variable Stars (Kholopov et al., 1982).

  While working on field variable stars around EK Lac I have noticed that chart
referring to NSV 14025 in fact refers to EK Lac, although the stated coordinates are
about 7' off the EK Lac position. While checking the literature it became clear that
Brun has overlooked in 1964 the identity of his star with EK Lac, already named
12 years earlier. This identity was overlooked also by compilers of NSV. As finding
charts are available for both stars, their identity is clear.

  As EK Lac is identical with GSC 3613.1331 the J2000.0 coordinates were easily
found (see Table 1). These coordinates are consistent with those given by Plaut
(1977). The remaining difference may have origin in proper motion, as the epoch
differs by 81 years. Finding chart (see Figure 1) was adapted from Atlas Stellarum
(Vehrenberg, 1970).

Table 1: Comparative table of original data for NSV 14025, GSC 3613.1331 and
EK Lac. Data concerning NSV 14025 are from NSV, data for EK Lac are from
GCVS, for EK Lac (Plaut) are by Plaut (1977) and data for GSC 3613.1331 are from
GSC. Photometric system code 1 for GSC represents the Kodak IIa-D plate with
W12 filter. Coordinates printed in italics were computed from the above stated data
sources.



 In cross-reference tables of NSV catalogue NSV 14025 is stated to be identical
with BD+48d3603. Regrettably this identification, based on the coordinates reported
by Brun, is not valid. This BD star, according to Brun's chart, is the star 1' NE
with respect to the variable, but this is incorrect too, because BD+48d3603 is in
fact about 7' E-SE from EK Lac. The BD star nearest to EK Lac is BD+48d3599,
located 1.7' north of variable, but no bright star can be found in this place. It is a
question, whether BD+48d3599 should be identified with EK Lac or its only slightly
brighter neighbour, because they are both at the same distance from the reported
position of BD+48d3599.

  Following cross-identifications are valid: EK Lac = GSC 3613.1331 = SVS 1114
= Brun 29 = Cat ph 22h06m +49d No108 = Cat ph 22h00m +50d No529 = NSV 14025.
