While observing today, I noticed a bright group of prominences on the approaching limb, at around 26 degrees south.  The tight grouping in conjunction with the activity level is similar to that seen with other active regions just behind the limb.  I checked the STEREO site, and sure enough there appears to be an active region which should come into view in about 72 hours.  Maybe the drought is finally over.

I was overjoy when I finally saw a sunspot popped up : ) I don't have an HA scope but I love seeing sunspots until I can set aside the extra cash for one.

This group erupted in the past 12 hours.  The prominence group is still there, belonging to an active region still over the horizon.  It looks like we are about to have two ARs.

To what website does one go to lookup the new sunspot numbers? My Google search wasn't successful.

Thank you. I visited a couple of government sites but didn't find that page.

SDO/HMI continuum image showing intense faculae but no

spots and SDO/HMI magnetogram of the same area showing

white North polarity lagging black South polarity.  Since this

feature is in the sun's southern hemisphere. the polarity

sequence is just the opposite of the sequence for AR12759

in the sun's northern hemisphere.  AR12759 is reputed to

be sunspot cycle 25.

Cheers,

Not seeing any spots or pores (at this stage) on the hi-res NASA images this morning, suggests it's just a region of plage less than 1500 gauss field strength - hence no spots, maybe it will develop into an active region?  There does appear to be something more substantial following it on STEREO though which looks more developed - think that one has more potential.  Either way is all cycle 25 activity.
