Solar Optics This photo was taken during the evening hours of April 10 looking west. It shows a halo around the sun caused by sunlight being bent through flat hexagonal ice crystals high in the atmosphere. Look carefully at the top of the arc to see the tangent arc. The brighter spot at the right of the halo is a sundog. Also produced (see bottom photo) is a more rare circumzenithal arc. It is a bit difficult to see but look just above the label.
Italy Earthquake Kills Over 270 The deadly earthquake that struck L'Aquila, Italy continues to take its toll with over 150 deaths reported and tens of thousands homeless. The 6.3 magnitude earthquake struck the town of L'Aquila, some 75 miles northeast of Rome, constructed primarily of mortar-type material. Below is the seismogram of the event as recorded here at Delta Community College. Due to a strong weather system moving through the area with high winds, the trace is not of good quality.
Chilean Volcano, Llaima, Continues to Erupt Residents around the Chilean Volcano, Llaima, were evacuated as the volcano continue erupting ash and lava. Below are two images from Delta Community College's GVAR GOES 12 receiving system showing the ash cloud in the visible image on top and the hot spot as indicated from the near-infrared image on bottom. The volcano, was proving to be quite explosive hurling materials up to 600 meters above the crater and spewing a flow of lava more than 1000 meters long. Continuous images can be found by clicking HERE and clicking on the volcano links on that page.
Minnie Ruffin Elementary Students Learn about Rocks & Minerals Professor Tiffany Green gave Minnie Ruffin elementary students a lesson about how rocks and minerals form within the earth. Professor Green demonstrated, using chocolate, how rocks melt deep within the earth and then harden. Of course, the best part was eating the results!
Lenwill Elementary Students Become Stormwise Professor Don Wheeler gave a storm chasing presentation to the fourth grade class at Lenwill Elementary in West Monroe. The students watched some storm chasing video, discussed severe storm safety, and played with a mini-tornado.
On Top of Louisiana! Driskill Mountain - Elevation 535 ft. Having climbed in Rocky Mountain National Park and driven Pike's Peak (elevation 14,110ft), Driskill Mountain, a mere 535ft, is, well..., the highest point in Louisiana! The summit is located south of Arcadia in Bienville Parish and ranks 48th in elevation among all states. Florida's Britton Hill and Delaware's Ebright Azimuth are lower. None-the-less, it was fun making the 1.5 mile hike up the mountain. Another peak, Gentry Hill at 524ft, actually appears before Driskill. Hikers in the past used to mistake it for Driskill; however, the landowners now have plenty of markings to the true Driskill summit.
