Space-VLBI observations of compact structures in OH masers with high sensi-

tivity.
ABSTRACT:
We request 8 hours of Arecibo time for a non-imaging space-VLBI observations of two most compact OH masers with RadioAstron. The main goal of this pro ject is to estimate correlated flux density, size and brightness temperature of the most compact maser spots. Successful RA-Arecibo measurements will provide space-ground baselines ranging from about 0.2 to more than 10 Earth diameters, and give the valuable limits on the brightness temperatures and the sizes of individual spots. This proposal is submitted as part of the Radioastron early science program.
