COMMENT: Maximum usable frequencies (MUFs) on UT day 26-Nov were
15% depressed to near predicted monthly values. The mild ionospheric
depression is probably in association with a mild increase in
regional geomagnetic activity induced by a coronal hole wind
stream. MUFs are expected to be depressed 10-15% to near predicted
monthly values over 27-28 Nov.
