And there's practically no hope that it's going to get brighter as it recedes from the sun and earth now, unless something unexpected happens. Here I slightly increased the brightness on a single 30 sec taken at 9:42 pm to see the comet, barely, and two 8th mag stars.Īs you can see, the comet is much fainter. It is NOT unaided eye visible, despite some reports to that effect. See the satellite and space-station views of various shorelines from across the United States. But even if you're a regular at your local swimming hole, you probably haven't seen too many beaches from this perspective. Summer is beach season in the northern hemisphere. I compare it to M51 the Whirlpool galaxy. NASA Earth Observatory Goes to the Beach. 1.7 degrees across.Īnd now, to answer the question. Begin your Earthdata exploration by clicking on any of the discipline icons above. The Earth Science Data Systems (ESDS) Program provides full and open access to NASA’s collection of Earth science data for understanding and protecting our home planet. There is distortion in star magnitudes due to histogram equalization, so comparing the brightness between objects will not be accurate. Your Gateway to NASA Earth Observation Data. Lots of processing to reduce the light pollution glow, and reduce noise. Only two image sequences were saved, and this was the best one, taken at 8:42 pm. NASA Earth Observatory NASA’s Climate Portal NASA Earth Science Division For Kids: About Earth Quick Facts Day 23.9 hours. I tried to take a series of images, but something went wrong, and I had to apply histogram equalization, a drastic measure, to get anything to show on the images ! It seemed to work, and I was able to stack most of the images. Trailing occurred within a minute, so I had to keep exposures to 30 seconds. EOSDIS makes the agency's large repository of data accessible and freely available to the public. Worldview is part of NASA’s Earth Observing System Data and Information System. Visually, the comet was a little brighter than last Wednesday, but not much bigger. The NASA Worldview app provides a satellite's perspective of the planet as it looks today and as it has in the past through daily satellite images. Perhaps some word got out that this night, the comet would be closest to the earth, 22 million miles away. At one point or two I had to ask people to leave as soon as they got their view of the comet, but I also encouraged them to take a long look. Tim warned me that he got inquiries as to whether we could see the comet that night, and we had a moderate increase in visitors. Lamont-Doherty Earth Observatory61 Route 9W Palisades, NY 10964. Haze of course, and lots of light pollution. No wind, but very cold, although not as cold as Griffith was Monday. Credit: Garvey Ranch Park Observatory - Dave Nakamoto/Telescope Operator
