Abstract
Measurements of the general magnetic fields of active, late-type stars obta ined with the 2.6-m Shain telescope of the Crimean Astrophysical Observator y are reported. Statistically significant values of the magnetic fields of E Eri acid 61 Cyg A have been detected. The magnetic fields range from -10 to 21 G. The magnetic-field values for E Eri and 61 Cyg A exceed the solar field by an order of magnitude; E Eri is more active than the Sun, while 61 Cyg A has approximately the same activity level as the Sun. There: is some evidence for variations in the general magnetic fields of these stars asso ciated with their axial rotation. (C) 2001 MAIK "Nauka/Interperiodica".
