GEOMAGNETIC/SOLAR FIELDS

The geomagnetic field remained at quiet conditions for most of
Sept. 18. A moderate geomagnetic storm began about 18:00 UT which
was continuing at this writing. This storm may affect seismicity
within 20 degrees of 75W and 105E a region which contains many
seismic areas. At the moment any affects, however are likely to
be minimal.

TROPICAL STORMS

Tropical Storm Felix remains stationary in the Central north
Atlantic Ocean. It is expected to dissipate to a tropical depression
in the next 3 days. For Tracking information see:

Tropical Storm Gabrielle continued to move intor the North
Atlantic Ocean and away from the North American mainland today.
The current mild earthquakes in Quebec and northern New England
may be related to this storm moving east of this area. For
