It appears that I missed seeing a dual pair of CMEs (coronal mass
ejections) on the Sun today. It took at place at 1154 UT. My session
began at 1853 UT. Fantastic footage of it can be seen here by SOHO
coronagraph.

AR 1084 still looks like a spiral galaxy (or a chicken eye with the wide
yellow/pink skin wrinkled around the pupil). A fantastic
filament/prominence reached over the limb in the SW. The filament was
thick and fibrous reaching out to the west and on either end, long and
slender.

Riser, my regular solar buddy, aka 14-year old Rhodesian Ridgeback, took
a pretty hard fall today and had to watch me observe from a distance in
the comfort of the shade at the top of the hill. He’s resting
comfortably now on a very thick duvet. Poor ol’ boy.

Object name: Sun.
Object type: Full disk in Ha line.
Location: Peristeri (GREECE)
Date: 13 June 2010
Media: Used laptop.

The seeing is not good but i make an observation and i see many thinks.First of all a great detached prominence at the NW of the disk. My goodness she`s great. I see one only sunspot on the region 1081 and a marvelous filament like a hook near the region 1080.The disk has to much small Q.R.Filaments in different shapes.

Used my coronado maxscope SM 60mm D.S 0.5A Ha on EQ5 base together with eyepiece Nagler 9mm.

Paul had a late night imaging so I brought the dogs outside with me, puppies included, to keep it quiet in the house for him. This, of course, meant lots of extra paws running around the observatory floor instead of just the steady snoring of Riser, my regular observing buddy. The views were shaking so badly that I finally gave up and tore down the rig, resetting it back up in the grass. I should have done that to begin with I suppose since seeing wasn’t the greatest and would have been a lot worse in the observatory, especially with the temps rising so quickly after our freeze last night.

There were quite a few features to concentrate on, but what really caught my eye were two areas of filaments in the NE quadrant. The transparency and seeing were just poor enough that I really struggled with pulling any detail out of the prominences on that section of the limb. I didn’t want to miss out trying to capture them as they reached inward across the disk, forming a beautiful display of soft looking filaments. Then even further inward reaching toward the center, the details were sharper with the next set of filaments.

I set up outside of the observatory today since the Sun was moving over the SW tree line and I didn’t want to rush my observing session. I had planned on putting in the cold crops in the garden but just couldn’t resist observing instead.

The active regions and filaments were tempting, but it had been so long since I’ve done close up prominence studies that I decided to concentrate on two limb areas instead. At the beginning of the session, the SW had a larger prominence that looked like a comma hovering over a crooked finger. I decided to move to the SE limb instead because what appeared to be a very bright hedgerow prominence with a smaller prominence beside it, turned out to a very wide set of prominences connected together, with over half of it so faint it was difficult to tease the detail out with the poorer seeing conditions at the beginning of the session.

Seeing gradually improved and I decided to go for a second sketch and just couldn’t help nabbing that comma prominence. It had already changed its shape to where it was no longer a comma, but a large loop instead. I was only able to make out the faintest portion of the loop with my Sol-Survivor cover completely shut around my head and eyepiece.

SW prominence at first glance looked detached. Increasing mag and waiting for steady seeing, I could make out fainter portions of the prominence that reached the limb. There were a few brighter prominence regions scattered about, but nothing of great significance, especially after the magnificent NW prominence last week.

AR 11057 stood out immediately with two dark areas and bright plage. Panning the FOV brought out another bright plage area on the WNW area just 10 deg in from limb. This could possibly be a remnant of 11056. Toward the southern-middle of the disk, brighter little clusters of plage scattered the area, as well a plage to the NW about 40 deg in from the limb. There were a few filaments but the one that really caught my eye was a wide V-shaped one to the SE. I had to tweak the Etalons to bring out the full structure of what first appeared as a single line of filament.

Sketch and Details by Les Cowley

For at least three days April 8-10, 2010 a large and ever-changing prominence rotated into view over the Sun’s NE limb. Its extent in solar longitude must therefore be considerable. Here is its appearance 09:00 UT on 10th April. Sketched directly at the eyepiece of a Solarmax 60 single stacked H-alpha scope 50 – 80X.
