IMERSA SUMMIT
Yesterday at the IMERSA Summit. Chuck Rau from Seiler Instruments, representing ZEISS in the United States and Canada talked about professional consultant work in our field at the System Matters session and may have triggered a discussion on honest marketing comparing 8k fulldome systems (actually 6.5k) with "true" 8k systems. It should be in the interest of customers and all partners in the industry to market correct numbers, also knowing that resolution is only one point in the spec of fulldome systems. Image quality and good perfomance are depending on many other aspects of hardware and software.
Good to have such meetings to avoid confusions.

DELICATE BALLET
A solar prominence gathered itself into a twisting cone, then rose up and broke apart in a delicate dance of plasma above the sun (Feb. 20, 2017). The event, observed in a wavelength of extreme ultraviolet light, lasted just about four hours. Prominences are unstable clouds of plasma suspended above the sun's surface by magnetic forces. This kind of event is not uncommon. The brighter area near the bottom of the images is an active region.

JOVIAN ART
NASA’s Juno spacecraft skimmed the upper wisps of Jupiter’s atmosphere when JunoCam snapped this image on Feb. 2 at 5:13 a.m. PT (8:13 a.m. ET), from an altitude of about 9,000 miles (14,500 kilometers) above the giant planet’s swirling cloudtops.
Streams of clouds spin off a rotating oval-shaped cloud system in the Jovian southern hemisphere. Citizen scientist Roman Tkachenko reconstructed the color and cropped the image to draw viewers’ eyes to the storm and the turbulence around it.
JunoCam's raw images are available at www.missionjuno.swri.edu/junocam for the public to peruse and process into image products.

ALL PLANETS PANORAMA Image Credit & Copyright: Tunç Tezel (TWAN)
For 360 degrees, a view along the plane of the ecliptic is captured in this remarkable panorama, with seven planets in a starry sky. The mosaic was constructed using images taken during January 24-26, from Nacpan Beach, El Nido in Palawan, Philippines. It covers the eastern horizon (left) in dark early morning hours and the western horizon in evening skies. While the ecliptic runs along the middle traced by a faint band of zodiacal light, the Milky Way also cuts at angles through the frame. Clouds and the Moon join fleeting planet Mercury in the east. Yellowish Saturn, bright star Antares, and Jupiter lie near the ecliptic farther right. Hugging the ecliptic near center are Leo's alpha star Regulus and star cluster M44. The evening planets gathered along the ecliptic above the western horizon, are faint Uranus, ruddy Mars, brilliant Venus, and even fainter Neptune. A well labeled version of the panorama can be viewed by sliding your cursor over the picture, or just following this link.
