Downgraded from magnitude 6.7 which is a little surprising seeing that all the tensor solutions at the time were 6.7 Mw and the Global CMT Project moment tensor is also 6.7 Mw. GeoFon has manually revised to 6.6 Mw as well.

And yes it was upgraded again to 6.7 Mw in the ANSS catalogue.

Forecast – Report of Solar and Geophysical Activity

: Product: 0427RSGA.txt

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 118 Issued at 2200Z on 27 Apr 2012
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was at moderate levels due to an M1/1n
flare at 27/0824Z from Region 1466 (N11W38). Other activity
consisted of single, low-level C-class flares from Regions 1459
(S19W88), 1465 (S17W53), 1467 (N11E32), 1469 (S24E28) and 1466.
During the period, Region 1465 developed into a beta-gamma-delta
magnetic configuration while the remaining regions showed little
change. Numerous non-Earth directed CMEs were observed off the SW
limb over the past 24 hours, all originating from old Region 1462
(S25, L=139) which rotated around the west on 24 April.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a slight chance for M-class activity for the next three days
(28 - 30 April).
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was at quiet to unsettled levels. Through the
period, ACE solar wind velocities steadily decreased from about 560
km/s to near 500km/s while the Bz component of the interplanetary
magnetic field was variable between +/-4 nT. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels throughout
the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at predominately quiet levels for the next three days
(28 - 30 April).
