Dear Colleagues, V. Simon (Ondrejov Observatory) reported his obervarions to us. According to his report, he took data mainly in R-filter and several images in V and I filters, so they will be helpful for determination of the color changes on long time scales. We have already received his data on JD 2451637.4674. Y. Lipkin (Wise Observatory) also reported his observations to us. We have already received his data on JD 2451676, 2451678, 2451679, and 2451680. We will re-analyze the data including them and report the result later in vsnet-campaign. Regards, Makoto Uemura
