Dear colleagues, I examined VRI photometry of the fields of DQ Ser, DT Ser, LL Cas, NSV 11776, V335 Vul, V471 Per, StHa 32, 55, 149, 164, 180 and 190 taken with 40cm telescope at Brno observatory in 2002 (some data were taken together with Petr Sobotka and Jan Skalicky). The images were processed automatically with respect to comparison stars measured by Henden (Henden & Munari 2000). The field photometry was searched for new variable stars using algorithm described e.g. in Pojmanski, 2000 (astro-ph/0005236), and implemented in VARFIND by Lukas Kral (http://kral.astronomy.cz/soft/varfind/). Two new variable stars were revealed. Pej 012 in the field of DQ Ser RA = 18:44:25.5, Dec = +05:00:13 (J2000), the star is not in USNO A2.0. Coordinates were measured on one of my I band images using Astrometrica and USNO A2.0 as reference. The star is very red but apart from past discoveries, this one has high amplitude, probably a Mira type variable star. Nightly averages: 20020612.9116 13.67Ic 20020705.9035 13.43Ic 20020722.8716 12.91Ic 20020819.8380 12.51Ic 20020830.8176 12.36Ic 20021026.7435 11.87Ic 20020830.8173 14.91Rc 20021026.7432 14.27Rc Pej 013 = GSC 2128 0732 in the field of V335 Vul RA = 19:23:25.9, Dec = +24:31:10, Tyc2 gives B-V = 0.59 The star is also a comparison star C on MEDUZA chart for V335 Vul. This star is probably some kind of short period variable. I computed nightly averages and this should not matter much as the usual time span of the individual points is about 5 minutes: 20020203.1859 9.67Ic 20020306.1235 9.55Ic 20020313.1063 9.58Ic 20020330.0571 9.64Ic 20020331.0758 9.60Ic 20020406.0360 9.57Ic 20020422.0690 9.60Ic 20020430.9878 9.59Ic 20020507.9845 9.57Ic 20020518.9583 9.67Ic 20020603.9291 9.56Ic 20020612.9714 9.54Ic 20020624.8480 9.62Ic 20020705.9334 9.47Ic 20020720.8407 9.52Ic 20020723.0230 9.51Ic 20020727.9615 9.60Ic 20020819.9565 9.59Ic 20020830.8808 9.59Ic 20021026.8544 9.54Ic 20021231.7534 9.58Ic 20030105.6931 9.56Ic 20020203.1900 10.07Rc 20020306.1211 9.92Rc 20020313.1085 9.94Rc 20020330.0597 10.04Rc 20020331.0780 9.97Rc 20020406.0383 9.97Rc 20020422.0716 9.96Rc 20020430.9903 9.93Rc 20020507.9868 9.94Rc 20020518.9610 10.07Rc 20020603.9305 9.95Rc 20020612.9725 9.91Rc 20020624.8489 10.00Rc 20020705.9344 9.86Rc 20020720.8416 9.88Rc 20020723.0243 9.90Rc 20020727.9613 9.96Rc 20020819.9563 9.96Rc 20020830.8806 9.95Rc 20021026.8542 9.93Rc 20030105.6929 9.96Rc 20020203.1968 10.43Vc 20020306.1180 10.31Vc 20020313.1116 10.32Vc 20020330.0637 10.41Vc 20020331.0804 10.34Vc 20020406.0416 10.39Vc 20020422.0838 10.35Vc 20020430.9945 10.34Vc 20020507.9899 10.35Vc 20020518.9751 10.43Vc 20020603.9333 10.34Vc 20020612.9742 10.32Vc 20020624.8506 10.34Vc 20020705.9363 10.27Vc 20020720.8431 10.30Vc 20020723.0262 10.27Vc 20020727.9611 10.34Vc 20020819.9562 10.33Vc 20020830.8804 10.32Vc 20021026.8541 10.32Vc 20030105.6929 10.32Vc Unfortunately, no new obvious variable stars in other fields.
