SIDC - Solar Influences Data Center Geomagnetic storm severity info (K-Index) NOAA / Space Weather Prediction Center The K-index is a code that is related to the maximum fluctuations of horizontal components observed on a magnetometer relative to a quiet day, during a three-hour interval. The conversion table from maximum fluctuation (nT) to K-index, varies from observatory to observatory in such a way that the historical rate of occurrence of certain levels of K are about the same at all observatories. In practice this means that observatories at higher geomagnetic latitude require higher levels of fluctuation for a given K-index. At SWPC, we monitor the preliminary values of the K-index, minute by minute, from a network of observatories that relay data in near-real time. The relationship between K, Kp, and estimated Kp The official planetary Kp index is derived by calculating a weighted average of K-indices from a network of geomagnetic observatories. In addition, the end-of-period NOAA estimated Kp index is used on our announcements and appears on our web site.

Cold and Spellbinding: An Alignment of Planets in the Sunset Sky Cold and Spellbinding: An Alignment of Planets in the Sunset Sky Feb. 17, 2012: Note to sky watchers: Put on your winter coats. What you’re about to read might make you feel an uncontrollable urge to dash outside. The brightest planets in the solar system are lining up in the evening sky, and you can see the formation—some of it at least—tonight. Go out at sunset and look west. If you go out at the same time tomorrow, the view improves, because Venus and Jupiter are converging. A special night to look is Saturday, Feb. 25th, when the crescent Moon moves in to form a slender heavenly triangle with Venus, Jupiter and the Moon as vertices (sky map). After hopping from Venus to Jupiter in late February, the Moon exits stage left, but the show is far from over. In March, Venus and Jupiter continue their relentless convergence until, on March 12th and 13th, the duo lie only three degrees apart—a spectacular double beacon in the sunset sky (sky map).

These gigantic bursts of radiation cannot pass through Earth's atmosphere to harm humans on the ground, however they can disrupt the atmosphere and disrupt GPS and communications signals. In this case, it appears the flare is strong enough to potentially cause some radio communication blackouts. It also produced increased solar energetic proton radiation -- enough to affect humans in space if they do not protect themselves. 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.

AR15 Scopes | Tactical Rifle Scopes | AR Scopes | Sniper Scopes Zen Cart(R) Tutorials and FAQs - How do I rename my Admin folder to prevent... While access to your admin area is protected by the requirement of your admin password, it is recommended for additional security that you rename your admin directory after installation. This way, it will be significantly harder for hackers to find your admin area or attempt any attack on breaking into it. (Before making the following changes, make sure to have a current backup of your files and your database.) You're going to do three steps: A) edit the configure.php settings and upload them, B) rename the admin folder, C) test login to the new folder. Details are below: A - configure.php - If you are using v1.5, go to step B. There is no need to alter the admin configure.php in v1.5.x when renaming your admin folder. B - Rename the Admin folder Using your FTP software or your webhost's File Manager , find your Zen Cart /admin/ directory . NOTE: DO NOT advertise this new foldername, else you defeat the entire purpose of renaming it. C - Login to your admin using the new URL And:
