Anyone looking at the Sun with enough magnification will easily spot the main components of Active Region 2595 along one of the limbs. For a somewhat blocked western horizon look before 4:37pm. For a mostly clear western horizon try before 5:49pm.

The 2016 Sun was fun for me. Below are my notes, listing start times of viewing...
*3 January, 3:43pm CST = I did not see 2476, 2477 or 2478 with a solar viewer. I certainly did not see 2473 (responsible for that M2.3 flare); I cannot discern any noticeable dark area on SDO optical.
*4 January, 1:38pm CST = ARs 2477 and 2476 were visible with the Sunspotter (though the chain of small spots in 2476 were difficult). 2478 is between them, but I did not see it. Tom, Amy and Hayley looked; Tom took a picture.
*5 January, 2:58pm CST = I saw 2477 and that's all. Solar altitude ~21˚. 2476 looked like it dimished optically. Again I used the Sunspotter, having to raise the back half over the lip.
*10 January, 4:57pm CST = 2480 is the largest area available. I did not see it. (I failed to record the instrument used, but it was almost certainly a solar viewer.
*17 February, 3:12pm CST = With the Sunspotter, saw AR2501 and nothing else. A nice, dry time.
*18 February, 2:17pm CST = With a filtered 6" Orion Skyquest Dob at 48x, I didn't see 2502 or 2503 but did see (briefly) the "tiny" speck near 2501.
*15 March, 4:14pm CDT = With the Sunspotter I saw the formidable AR2519 and the largest two of the three separate areas comprising AR2521.
*19 September, 5:38pm CDT = I used a solar viewer. The "'pepper flakes" found at ARs 2592 and 2593 did not show up at 1x. It's not surprise.
*20 September, 3:36pm CDT = With a Sunspotter, I saw the large and medium components of AR2595 but not the small piece.
*28 September, 4:59pm CDT = I saw none of AR2597 with the solar viewer.
*30 September, 3:58pm CDT = No sign of 2597, though there wouldn't be anyway--it's on the extreme edge of the solar limb (used a solar viewer).
*1 October, 4:26pm CDT = Used a solar viewer; no sign of anything!
*3 October, 3:07pm CDT = Used a solar viewer; not a blessed thing--AR2598 too small.
*4 October, 3:27pm CDT = Nothing in the solar viewer, but the Sunspotter was something else. I saw the largest component of 2598 and the oblong shape of 2599.
*11 October, 3:51pm CDT = With the solar viewer I can't say I saw anything. With the Sunspotter the double-lobed 2599 and sole 2600 were seen with no difficulty. With the Orion Dob at 48x the view is astonishing--it shows so much more clarity than the Spaceweather capture. 2599 has three distinct sections of dark, with a smaller fourth dark area. ("Spaceweather" refers to Tony Phillip's site.)
*12 October, 4:32pm CDT = With the solar viewer, didn't see anything. With the Sunspotter, saw plenty. With the Orion Dob at 48x saw a sprinkling of points near the limb.
*14 October, 11:23am CDT = With the Sunspotter I saw AR2600. With the Orion Dob at 48x all three ARs were visible. With the Coronado Solar Max II the sunspots were easy to find, but there were no flares or prominences (just the mildest hedgerow action).
*17 October, 2:54pm CDT = With the solar viewer I saw nothing. With the Sunspotter I saw both dark components of 2602, and easily saw the elongation of 2600.
*25 October, 10:14am CDT = WIth the solar viewer I saw nothing. With the Sunspotter I saw the two largest components of 2603.

The barely impressive AR 2619 needs magnification. I looked with a solar viewer at 1:32pm CST and saw a wonderful scene of clouds passing in front of the Sun but no extensive sunspot activity.

The next public viewing session at HRPO will be from 12pm to 2pm on Saturday 28 January.
