COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 1310 Konkoly Observatory Budapest 1977 July 27 BV OBSERVATIONS OF THE DWARF CEPHEID EH Lib According to the programme of investigation of dwarf cepheids two-colour photoelectric observations of EH Lib were carried out in the years 1974-1976. Within 13 nights over 500 observations of the variable in the photometric system close to BV have been obtained. From these observations 11 moments of maximum light of EH Lib have been derived for each colour. The epochs and the deviations (O-C) are computed from the elements D3 GCVS, 1968: Max. J.D. = 2433438.6073 + 0.088413276E. The moments of maxima, epochs and deviations observed are as follows: Max. J.D. E (O-C) 2442162.5182 98672 -0.0040 B .5180 98672 -0.0041 V 182.4132 98897 -0.0018 B .4135 98897 -0.0015 V 541.4591 102958 -0.0023 B .4585 102958 -0.0029 V 544.3756 102991 -0.0034 B .3760 102991 -0.0030 V .4655 102992 -0.0019 B .4651 102992 -0.0023 V 577.4435 103365 -0.0021 B .4440 103365 -0.0016 V 871.5064 106691 -0.0017 B .5075 106691 -0.0006 V .5936: 106692 -0.0029: B .5929: 106692 -0.0036: V 872.4775 106702 -0.0032 B .4770 106702 -0.0037 V .5654 106703 -0.0037 B .5661 106703 -0.0030 V 874.5107 106725 -0.0035 B .5107 106725 -0.0035 V The observations support the conclusion made on the variability of the period of light variations of EH Lib.
