SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids - Nightly Philips SPC900NC uncovered ToUcam SPC900NC Back to main page With discontinuing the ToUcam Pro II PCVC840 a new camera had to be found to modify. The Philips SPC900NC seems a good new candidate. Here the story with pictures and comments. 1. 1. 2. Opening the camera is a bit more complicated than a ToUcam Pro 740 or 840, because it requires more steps. 3. 4. For how I did these tests I refer to the explanation on this page. the measured exposures of the SPC900NC at different exposure settings, framerates and 640x480 resolution. 5. To prepare for the long exposure mod several measurements must be done to know which signals have to be controlled. Because of the two board design with the processing and control components on different boards, there were high hopes that the long exposure signals could be connected to the large black connector, so that the lifting of pins and cutting of traces could be avoided. Furthermore: the modification I describe below is one of the many possible ways to do the long exposure mods.
Le Soleil - SpaceWeather live Real-time plots auroral activity Welcome on SpaceWeatherLive! Below you will find the status of the solar wind and the Interplanetary Magnetic Field (IMF) from the past two hours as measured by the ACE spacecraft. These parameters are the first parameters used to predict auroral activity. Observed Kp: 2o Predicted Kp: 2- (+78m Kp: 2+) Kiruna Magnetogram This magnetogram gives you the values measured by the ground station of Kiruna (Sweden, Europa). EPAM - Electron Proton and Alpha Monitor EPAM stands for the electron, proton and alpha monitoring and is an instrument on the ACE satellite that measures the electrons and protons that are sent with the solar wind.

SOLARHAM.com / Solar Cycle 24 / Spaceweather / Amateur Radio VHF Aurora Website - Nightly Kepler discovers 461 new planet candidates NASA's Kepler mission announced January 7 the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun's "habitable zone" — the region in the planetary system where liquid water might exist on the surface of a planet. Based on observations conducted from May 2009 to March 2011, the findings show a steady increase in the number of smaller-sized planet candidates and the number of stars with more than one candidate. "There is no better way to kick off the start of the Kepler extended mission than to discover more possible outposts on the frontier of potentially life-bearing worlds," said Christopher Burke of the SETI Institute in Mountain View, California. Since the last Kepler catalog was released in February 2012, the number of candidates discovered in the Kepler data has increased by 20 percent and now totals 2,740 potential planets orbiting 2,036 stars.
Sun Unleashes X6.9 Class Flare Sun Unleashes X6.9 Class Flare On August 9, 2011 at 3:48 a.m. EDT, the sun emitted an Earth-directed X6.9 flare, as measured by the NOAA GOES satellite. There was also a coronal mass ejection (CME) associated with this flare. Updates will be forthcoming if needed. Related Links: › Solar Flares: What does it take to be X-class?› Karen C. Helioviewer.org - Solar and heliospheric image visualization tool - Nightly Earth-sized planets: Two super-Earths found orbiting the same star. Image credit: David A. Aguilar (CfA) Scanning the heavens, you might very well miss the star Kepler-62. It’s a rather typical star, slightly smaller, cooler, and more orange than the Sun, much like tens of billions of other stars in our galaxy. But it holds a surprise: It’s orbited by at least five planets… and two of them are Earth-sized and orbit the star in its habitable zone! The two planets, called Kepler-62e and Kepler-62f, are both bigger than Earth, but not by much; they are 1.6 and 1.4 times the Earth’s diameter, respectively. Given the temperature and size of the parent star, this means that both planets are inside the zone around the star where water on the surface could be a liquid. Or it might not. Also, the best computer models we have, based on what we know about how planets form and change over time, indicate that these planets could very well have water on them (it is, after all, incredibly common both in our solar system and in the Universe at large).
