GSC 02976-00401 is a V=9.56 magnitude star with (B-V)=1.687. Its coordinates coincide with those of an infra-red source IRAS 07580+4235. Our 132 brightness measurements obtained during 30 night between September 24, 2002 and May 5, 2003 (comparisons: HD 67586 and HD 66469) clearly show variability of the star’s light. The light curve variability is apparently irregular and total observed amplitude is 0.33 mag.

BD+42 1814 (= SAO 42186 = GSC 02976-01660) is also an infra-red source. In the IRAS catalogue it is identified as IRAS 08046+4154. According to Simbad BD+42 1814 is a V=9.39 magnitude star with (B-V)=1.91, what makes it very red as for the spectral type of K5. The (B-V) color index calculated from TYCHO-2 data is much lower, 1.65 mag. The star was observed during 40 nights between September 24, 2002 and May 5, 2003. 175 data points were collected in total. The obtained light curve shows irregular light changes with total amplitude of 0.2 mag. Our comparison stars for this field were: HD 67586 and HD 66469.

HD 76190 (= BD+44 1803 = SAO 42604 = GSC 02989-00901) is a V=9.07 magnitude star with (B-V)=1.54 and spectral type of M2III. It is also an infra-red source IRAS 08527+4432. The star was observed during 40 between September 24, 2002 and May 5, 2003. 171 single data points were collected. We adopted HD 76191 and HD 76617 as comparison stars for this field. The total light-curve variation amplitude is 0.27 mag. During observed time interval the amplitude gradually decreased.
