Abstract:
Optical monitoring of S5 0716+714 was performed with a 60/90 Schmidt
telescope in 2003 November and December and 2004 January for studying
the variability of the object on short timescales. Because of the high
brightness of the source, we could carry out quasi-simultaneous
measurements in three bands with a temporal resolution of about 20min
by using one single telescope.
Description:
Our optical monitoring program was performed on a 60/90 Schmidt
telescope located at the Xinglong Station of the National Astronomical
Observatories of China (NAOC). Our monitoring of S5 0716+714 was
divided into two periods, one from 2003 November 8 to 18 (six nights,
in fact, as a result of weather conditions) and the other from 2003
December 30 to 2004 January 5 (seven successive nights). The first
period (period 1) covered the duration of the INTEGRAL observation,
and the second period (period 2) was an extension of period 1.
