UPDATE 04/17/2012 16:00 UTC
A few C-class flares and an M-class flare were observed during the past 24 hours. We expect active conditions with C-class and M-class flares possible. An M1.7 flare was observed by GOES on April 16, peaking at 17:40 UT. The flare originated from an active region (Catania 03; old Sunspot 1442/43) which appeared now on the east limb. The accompanying CME propagated with the speed of about 1300 km/s.
Reporting to Solen.info:
A partial halo CME was observed after the M1 event in region S1592. There's a chance of a flank CME impact on April 19http://www.solen.info/solar/
Region 1459 increased at a more rapid pace to a FHI group at 260 millionths, making it the largest visible sunspot group
New region S1592 [N12E80](associated to the M1 event) rotated into view at the northeast limb and will be soon numbered 1461. nFurther C class and a slight chance of an M class flare are possible over the coming days
Video shows you the increasing Region 1459:

The Coronal Hole High Speed Stream winds have stired up a G1 storm and a mid latitude Aurora. Will you be able to see the Aurora from your location? Click here OVATION Auroral Forecast, to see where the Aurora can be see from. Research more about the Aurora in our Q an A guides Q&A/Guides. The effects of the CHHSS are expected to continue through the 13th before diminishing on the 14th and returning to quiet levels on the 15th.

Beginning at approximately 19:54UTC on April 10 2012 a new Sunspot Region exploded onto the surface in a spectacular display from new region S1576 [N07E23], having just emerged with an east-west inversion line. This region is not yet numbered by NOAA/SWPC, but it is anticipated that it will be numbered Region 1455 later on today. This new region is shown imaged left by the SDO Magnetogram. An animated gif of the Magnetogram showing the rapid development of this region is below and can be viewed by clicking on the image. This region will be rotating toward a more Earth aligned position over the next couple of days increasing the chances of activity from this region becoming geoeffective.
