I missed good weather! Today we have plenty of sunshine! Seeing is less favorable at 3/10, I would rate it. Transparency is 6-7/10, very good in our standard.

Full disc surface detail, full disc prominence (normal + pushed) were taken.

1335 (GMT+8), surface detail centric exposure, prominence push processed:-


1337 (GMT+8), surface detail centric exposure, prominence push processed:-


1338 (GMT+8), prominence centric exposure:-


1339 (GMT+8), this big prominence is relatively dimmer, so I pushed the exposure to pick up the dimmer part:-


And then a Tele Vue 2x barlows is added to push up the image scale, and a 3*2 mosaic was attempted, finally a closeup of the dim but big prominence was also taken. The mosaic was basically failed, they cannot be stitched together after processing:-

1347 (GMT+8), that prominence again, close up:-


The lower part of the mosaic, consisting of two parts, this is the best of the batch:-


The middle part of the mosaic, consisting of two parts, just as record:-


The upper part of the mosaic, consisting of two parts, just as record:-


Next, I pulled out my C5/PST setup for close up...

1401 (GMT+8), very poor contrast, part of the aperture blocked by the wall:-


1404 (GMT+8), very poor contrast, part of the aperture blocked by the wall:-


1408 (GMT+8), 2x barlows added, very poor contrast, part of the aperture blocked by the wall, and seeing did not support this image scale at all:-
