CCD Observations of Some Variable Stars
Using 1024x1024 pixels CCD camera of ChungBuk National University Observatory (CBNUO), 62 photometric observations were made on January 11-12, 1993. A time of minimum lights of U Cep was determined as JD Hel 2448999.2274 from our data. On October 21-22 in 1993, CCD photometry in V and R for GW Cephe...

| description | Using 1024x1024 pixels CCD camera of ChungBuk National University Observatory (CBNUO), 62 photometric observations were made on January 11-12, 1993. A time of minimum lights of U Cep was determined as JD Hel 2448999.2274 from our data. On October 21-22 in 1993, CCD photometry in V and R for GW Cephei and V700 Cygni was carried out with 309 x 584 pixels cooled CCD system of Behlen Observatory, University of Nebraska-Lincoln(BOUNL) and 168 observations were obtained. From the data time of minimum lights JD Hel 2449282.8485 for GW Cep and JD Hel 2449282.7979 were determined. To develop a new CCD system of CBNUO, the CCD photometry method using at CBNUO is compared with at BOUNL. |
