![]() ![]() K-index Alerts are issued when the NOAA estimated Kp-indices reach 4, 5, 6, 7, 8, or 9. K-index Warnings are issued when NOAA estimated Kp-indices of 4, 5, 6, and 7 or greater are expected. Important magnetometer observations are also contributed by the Institut de Physique du Globe de Paris and the Korean Space Weather Center K-index Watches are issued when the highest predicted NOAA estimated Kp-indices for a day are K = 5, 6, 7, or >= 8 and is reported in terms of the NOAA G scale. Geological Survey, Natural Resources Canada (NRCAN), the British Geological Survey, the German Research Centre for Geosciences (GFZ), and Geoscience Australia. These data are made available thanks to the cooperative efforts between SWPC and data providers around the world, which currently includes the U.S. The Estimated 3-hour Planetary Kp-index is derived at the NOAA Space Weather Prediction Center using data from the following ground-based magnetometers: Sitka, Alaska Meanook, Canada Ottawa, Canada Fredericksburg, Virginia Hartland, UK Wingst, Germany Niemegk, Germany and Canberra, Australia.

"It could be that these events, although extremely rare, are so energetic that they are key processes to how the centres of galaxies change over time," added Philip Wiseman. This could reveal its surface shape, temperature and the mysterious processes generating the bright light.īut the fact remains that nothing on this scale has ever been witnessed before, as evident from the fact that flashes from this event continue to illuminate telescope networks worldwide. Researchers are now studying the event in more detail by scanning across wavelengths. Metrologist Eric Berger predicts there will be 3-6. At this stage, the organization warns against nuisance street flooding. While the exact cause of this blinding explosion remains unclear, researchers believe it is most likely the result of a supermassive black hole gorging on a cloud of gas and dust thousands of times larger than our Sun.Īnd as the black hole clumsily gobbles up chunks of this cloud, it is sending shivers and shockwaves of fear down its remnants as well as the dusty ring surrounding the black hole, setting off a giant explosion whose light is yet to die out! Space City Weather issued a Stage 1 flood alert starting at noon Monday. Nicknamed the Bayou City, Space City, H-Town, and the 713. However, one look at the extraordinary explosion blazing with the same intensity as quasars - some of the most radiant objects in the Universe - sent them scurrying for answers. Houston is the most populous city in Texas and in the Southern United States. It was flagged by their search algorithm while looking for a type of supernova. What's more, this unusually energetic interaction is releasing roughly 100 times the energy our Sun will release over its entire lifetime! If this isn’t a cry for attention, what is?ĭespite its freaky energy, astronomers were led to this stunning scene purely by chance. Lows on Friday night will drop into the upper 50s. Its flash was seen only for a fraction of the time, meaning the overall energy released by the AT2021lwx explosion is far greater. High temperatures on Friday may only reach the low to mid-60s, with continued mostly cloudy skies. For something to be bright for two-plus years was immediately very unusual," remarked lead author Philip Wiseman.įor context, astronomers discovered the most powerful gamma-ray burst ever seen last year. "Most supernovae and tidal disruption events only last for a couple of months before fading away. The Weather Channel - Local, state, and national weather forecasts and. It is burning about three times brighter than the most brilliant tidal disruption event - bright flashes that occur when black holes rip apart wandering stars - known to humankind. Space City Weather - Straightforward weather forecasts for the greater Houston area. A messy black hole about eight billion light-years away from Earth appears to have triggered the largest explosion in the Universe, and it has been spattering light for three years now!ĭubbed AT2021lwx, this cosmic event is ten times brighter than any known supernova. ![]()
