Mercury transit observed with Singer H-alpha full disk telescope on November 8, 2006 (MPEG 16.6 MBytes): Images taken with an Apogee KX4 CCD camera. A smaller version (MPEG 3.5 MBytes) of the movie can be found here. |

Movie of June 10, 2002 Solar Eclipse (MPEG 1.0 MBytes): Observed with Singer H-alpha full disk telescope and Apogee KX4 CCD camera. |

Mercury transit observed with Singer H-alpha full disk telescope on November 15, 1999 (MPEG 3.4 MBytes): The images were taken 20 seconds apart from 21:11 (first contact) to 22:10 UT (last contact). The images were captured with a Kodak MegaPlus 4.2 CCD camera. The spatial resolution is about 1 arcsec per pixel. Here we only show a small portion of the full disk images near the solar north pole. The field of view is approximately 470 arcsec x 170 arcsec or 340,000 km x 125,000 km on the Sun. |
|
Near IR Movie of Solar Granulation (MPEG 0.5 MBytes): A near IR movie at 1.56 µm of solar granulation obtained with the 65 cm vacuum-reflector. The exposure time was 0.1 ms with an image scale of 0.25 arcsec per pixel and the field of view of 62 arcsec x 47 arcsec. This 60 minute long time series was taken on March 12, 1999. |
|
Mini-Filament eruption on October 29th, 1997 (MPEG 0.7 Mbytes): This time series was derived from our contrast enhanced H-alpha full disk images. The field of view amounts to approximately 180 arcsec x 180 arcsec, and the mini-filament erupted almost at disk center. |
|
Movie April 22nd, 1996 (MPEG 0.7 Mbytes): NOAA region 7958, which produced numerous X-ray events (including one M-class), displayed very rapid growth from April 20th until it crossed the west limb on April 23rd. The images were taken with a Kodak MegaPlus 1.6 CCD and our narrow band holographic Accuwave H-alpha filter. |
|
Spectral Scan (MPEG 1 Mbytes): We scan a slit spectrograph to obtain 3D-data (2 spatial and one spectral dimension) of the Sun. The images are stored on optical disc and are processed off-line to produce images of line shift, line center intensity etc. We obtained 70000 images in 3 hours at our observing run in July 1995. Below is a short section from one of the scans showing the H-alpha line to the left and a simultaneous slit-jaw image to the right. |
|
Spicules at the limb (MPEG 0.5 Mbytes): Spicules are visible at the limb of the Sun in H-alpha. This movie shows time evolution of spicules obtained in off band H-alpha. The movie is rather short and it is thus wise to set the MPEG-viewer to loop. |
|
Movie from August 18th, 1995 (MPEG 0.2 Mbytes): A movie showing an erupting prominence at the East limb of the Sun. |
|
K-line movie (MPEG 0.7 Mbytes): A movie showing the BBSO daily Ca K-line images (January - May 1995). Limb-darkening and instrumental effects are removed. |
|
Moving penumbral waves (MPEG 0.3 Mbytes): A movie showing waves in the penumbra of a sunspot. The frames in this movie are unprocessed. |
|
Penumbral wave movie No. 2 (MPEG 1.4 Mbytes): The same movie as above showing penumbral waves in a sunspot, but now the images have been processed to remove the large-scale brightness variations to make the waves somewhat easier to see. |
|
Movie from July 20, 2002 (MPEG 2.8 Mbytes): Post flare loops from an X3.3 flare over the southeast limb. Taken from H-Alpha fulldisk observations. |
|
X4.8 Flare July 22, 2002 (MPEG 4.3 Mbytes): X4.8 Flare in region NOAA 0039 on July 22, 2002. Taken from H-Alpha fulldisk observations. |
