This rotated around the solar limb on the Friday Apr 8 and it has a dominant leading penumbral sunspot and a couple of smaller irregular followers.  Today (April 10) the main leading sunspot has an estimated area of 660 millionths and the whole group 830 millionths.  Observations and images are welcome for the TA solar notes.  The usual precautions are required for solar observing, including naked eye observations.
