Ha Live Kanzelhöhe almost Real-Time H-alpha / White-light and CaIIK Images . Display of the latest observed solar images with automatic updating.
Full size Kanzelhöhe Prominence Image from 2022-07-05, recorded with a 12-bit 2048 x 2048 pixel Pulnix TM-4200GE camera, size abt. 300kB. For these images the exposuretime of the camera is set to 50 Milliseconds (about 20 times of the normal exposure). The solar disc is removed and the outer parts are rescaled, additionally the solar disc is rotated (solar N up). These images are made in collaboration with the Astronomical Institute of the Slovak Academy of Sciences.
Full size Kanzelhöhe Synoptic white-light Image from 2022-07-05, observed at 546 nm (10 nm FWHM) with a 12-bit 2048 x 2048 pixel Pulnix TM-4200GE camera. Before 2009-01-12 JPEG image is downscaled to half-size, file sizes abt. 150kB, for newer dates it is presented in full-size (abt. 1200kB).
Full size Kanzelhöhe Normalized white-light Image from 2022-07-05, observed at 546 nm (10 nm FWHM) with a 12-bit 2048 x 2048 pixel Pulnix TM-4200GE camera. These images have been corrected by removing large scale asymmetries, and a limb darkening estimate has been subtracted to enhance the contrast. Before 2009-01-12 the JPEG image is downscaled to half-size, file sizes abt. 250kB., for newer dates it is presented in full-size (abt. 1000kB).
Full size Kanzelhöhe synoptic H-alpha Image from 2022-07-05, recorded with a 12-bit 2048 x 2048 pixel Pulnix TM-4200GE camera, size abt. 300kB. Before 2008-01-06 the images were obtained with a 14-bit, 2032 x 2032 pixel Apogee KX4 CCD camera, size abt. 200kB. There is also a half-sized image available. (70kB)

Full size Kanzelhöhe normalized H-alpha Image from 2022-07-05, recorded with a 12-bit 2048 x 2048 pixel Pulnix TM-4200GE camera. Before 2008-01-06 the images were obtained with a 14-bit, 2032 x 2032 pixel Apogee KX4 CCD camera. This image has been corrected by dark and flat field images, and the contrast is enhanced by dividing (TM4200GE) or subtracting (KX4) a limb darkening estimate, size abt. 400kB.
Full size Kanzelhöhe synoptic CaIIK Image from 2022-07-05, recorded with a 12-bit 2048 x 2048 pixel Pulnix TM-4200GE camera, size abt. 1200kB.
