Active Region NOAA 8844

The active region NOAA 8844 emerged at the solar surface on January 22-23, 2000.

Until the 24th it was apparently quiescent with only two, small, and stable sunspots.

On the 24th or early on the 25th, it started a rapid growth. The two main flux concentrations of opposite polarity separated rapidly from each other and new magnetic flux was constantly emerging from its center. The active region continued growing for only about 24 hours.

FGE started the observations of NOAA 8844 on January 25 (15 days after launch), at 15:19 UT and ended at 19:13 UT.

At the time of the observations the region was located approximately at 5°N, 30°W.


Movies and Animations

The movies above (animated gifs) show the evolution of the active region during the time span between Jan 25, 2000 15:50 UT and Jan 25, 2000 19:14 UT (3h 24min). The time difference between each frame, for the white light and the magnetogram movies (54 frames), is approximately 3.50 minutes, and about 7.5 minutes for the H-alpha and Doppler movies (28 frames). The image size is 90×90 arcseconds (approximately 65700×6570 Km). North is towards the upper right corner and West towards the lower right corner. Click on the thumbnails to view the movies.

These movies show the location and temporal evolution of the Ellerman Bombs relative to the White Light, Magnetogram, and Dopplergram, features. Ellerman Bombs are the small (~ 1 arcsec Ø) brightenigs that can be seen in the H-alpha-1 Å filtergrams, in the area between the two main sunspots.
