COMMENT: The Sun remains very quiet. A new active region is about to appear at
the S-E limb. However, no significant activity was observed behind the E limb
over the past few days by space coronal imagers (GOES/SXI, CORONAS/SPIRIT). The
overall solar activity is thus expected to remain low. The geomagnetic was quiet
to unsettled and is expected to remain so over the next 3 days, as no eruptive
transient nor coronal hole disturbances are expected. Thus: all quiet
conditions.
