Observations of stellar image motions with the Synchronous Network of Telescopes
Abstract
Stellar Image Motions (SIM) discovery became possible due to the use of the Synchronous Network of distant Telescopes (SNT), which presents an exciting new way for detecting the small-scale variability. The millimagnitude precision of ground-based stellar photometry and the milliarcsecond accuracy in coordinates of position measurements in the optics seem to be distant summits for most practitioners. SIM during the integration time can cause photometric errors and frustrate the exact position measurements. The main goal of this work was to detect the effect of image motions in the focal plane of several distant telescopes operating synchronously. Note that such an effect amounting to a few tenth arcsecond may be only marginally detected in the trivial round measurements.
