Solar prominence 31 October 2014

Short animation of the ever changing solar prominence. It consists of 38 frames at frame-rate of 15 fps. Still frames were acquired from 11:10 to 11:50 UT. Every still frame is registered and processed imaged, made out of 45 seconds long video. Seeing conditions were very poor.

Eta-Aquariids 2014

Eta-Aquariids are one of two meteor shower associated with Halley’s Comet. With the radiant in constellation Aquarius (located close to the stars that resemble Mercedes sign), this is southern hemisphere meteor shower. Eta-Aquariids are best seen by the observers located in the southern hemisphere. The radiant rises in the morning, so you are able to see those meteors only in the final two hours before dawn. Therefore you must observe from a location with low levels of light pollution in the east. The shower has very broad peak of maximum activity from 4th to 8th May. ZHR is variable from 40 to 130 as seen in last year’s outburst.

Within two days of observation I was able to capture only one meteor.

Sunspot AR1944

A few days ago, on New Year’s Day, a sunspot appeared over the western edge of the Sun. AR1944 is huge and actually consist of more than 50 individual sunspots, the largest of them is far larger than the Earth itself. It was possible to observe it using only unaided eye and proper solar filter (e.g. eclipse glasses).

It has been classified as having a beta-gamma-delta magnetic field and these fields are prone to instability that can produce X-class solar flares. During the rotation around the visible limb of the Sun it was quiet and produced only one major X1 flare.

During imaging the seeing was very poor and was even more obvious while imaging at higher focal ratios.

This giant spot is about to rotate off the face of the Sun, this was probably my first and last shot of it. But this is not the only obvious sunspot currently visible on the Sun. I managed to capture a few other.
