Remember the “Face on Mars”? (https://en.wikipedia.org/wiki/Cydonia_(region_of_Mars))
Well, here is one on the Sun!
Didn’t have chance to do anything but the briefest of imaging this morning, so we have ended up with a bit of a mosaic, but at least there is a surface feature!
Maybe I should report it to the “Sun” newspaper! Seems appropriate!
Forgot to post these…
From the morning of Wednesday 14th Feb.
Hand held Nikon D3 and Nikon 24-70mm f/2.8
The first at 7.22am
70mm ISO 200 1/125sec f/5.6
and the second at 7.26am
70mm ISO 200 1/160sec f/6.3
A light pillar..?
(From Wikipedia, the free encyclopedia)
An atmospheric optical phenomenon in the form of a vertical band of light which appears to extend above and/or below a light source. The effect is created by the reflection of light from numerous tiny ice crystals suspended in the atmosphere or clouds. The light can come from the Sun (usually when it is near or even below the horizon) in which case the phenomenon is called a sun pillar or solar pillar. It can also come from the Moon or from terrestrial sources such as streetlights.
See here for more details:
Today’s view shows the 10 o’clock prominence subsiding, but you can now see its associated filament.
I have also posted a collage of its progress over the last few days.
Some nice prominence development this morning. Seeing was pretty poor, but the final images aren’t too bad.
Yesterday, the Sun was completely blank. No spots, no prominences, no filaments. I wondered if that was it for a while!
However, we have prominences today (even one with a detached plasma cloud) – – -:
Back to calm. No spots and just 1 prominence system of note.
Now seems a good time to summarize spot 2699’s progress over the last 11 days or so:
Spot 2699 has now just about gone:
After a couple of days being clouded out, this morning was nice and clear. Spot 2699 is now approaching the receding limb.
Following recent discussions and comments, in this case I collected 5 images as 200 frame avis, 2 with barlow and 2 with focal reducer with the Lunt, swapped the 80mm onto the mount and then did a white light with the barlow. The whole process took 10 minutes from looking out of the window and seeing it was clear.
“On Feb. 12th, the magnetic canopy of sunspot AR2699 exploded–for more than 6 hours. The slow-motion blast produced a C1-class solar flare and hurled a coronal mass ejection (CME) almost directly toward Earth.
The CME is expected to reach Earth on Feb. 15th. NOAA forecasters say there is a 60% chance of G1-class geomagnetic storms with isolated periods of stronger G2 storming.
The effectiveness of the CME could be enhanced by a stream of solar wind that was already en route to Earth when the sunspot exploded. The solar wind is flowing from a large wedge-shaped hole in the sun’s atmosphere. If the approaching CME sweeps up material from that stream, snowplow-style, it could strike Earth’s magnetic field with extra mass and potency.
Arctic sky watchers should be alert for auroras when the CME arrives. If the coming storm intensifies to category G2, observers in northern-tier US states from Maine to Washington could see auroras as well. Stay tuned for updates”
