Typhoon Talim in VIIRS William Straka III
13-Sep-17 - 16:52UTC: Category 4 typhoon Talim is churning away in the Pacific, currently impacting the Ryukyu Islands and forecast to impact Kyushu in the next several days. Even with the Last Quarter moon (47% illumination) low on the horizon, that was enough moonlight to show some stunning details in the Day Night Band, such as the large eye as well as mesovorticies, and a couple of lightning streaks as well as some ship lights in the East China Sea.
Hurricane Maria William Straka III
20-Sep-17 - VIIRS I-Band 5 image for Hurricane Maria. At 2:13am (AST/EDT), Maria made a glancing blow to St Croix, just skinning the teeth of the western part of the island. Per the 2am Advisory, it was a Category 5 at the time, with winds of 165mph. Read more

Hurricane Harvey Mitch Goldberg / Sanmei Li (JPSS PGRR)
31-Aug-17 - On August 25 Hurricane Harvey made landfall near Rockport, Texas, as a Category 4 storm with winds of 130 mph. Afterwards, Harvey had degraded to a tropical storm. Over the next five days, the storm dumped feet of rain over most of southeast Texas. Some areas around Houston and Beuomont saw upwards of 4 feet of rain during this time. The left image shows Aug 31, 2017 Flood Detection Map for Houston Beaumount area generated from 375m VIIRS magery data. Read more.
Suomi NPP Captured the Eclipse! Curtis Seaman (CIRA)
21-Aug-17 - The August 21 eclipse was captured by the Suomi NPP polar satellite, which flew over the path of totality as it cross the Southeastern United States. S-NPP teams have contributed interesting images and data artifacts of the eclipse from the OMPS, VIIRS, and CrIS instruments. Read more.
Larsen C Ice Shelf Sheds a Big One! Jeff Key; William Straka III
14-Jul-17 - Antarctica just shed a very large piece of the Larsen C ice shelf. A block of ice the size of the U.S. state of Delaware broke off sometime between July 10 and 12. This block of ice is now an iceberg named A-68. VIIRS I5 false-color image (July 14, 2017, 04:30 UTC) clearly shows the iceberg (A-68) that had broken off the Larsen-C ice shelf, and a smaller iceberg breaking off of A-68.

18-Jun-17 - The VIIRS instrument on Suomi NPP captured the event. Plot of FRP (fire radiative power) for June 18th from NDE operational active fires product clearly shows the fire. left top image: June 18th VIIRS DNB image from Chris Elvidge's group.
Tropical Cyclone Donna William Straka III
7-May-17 - At ~1358Z May 7th, S-NPP was looking down at Tropical Cyclone Donna in the Coral Sea off the coast of Vanuatu. Donna, an out of season storm, formed on 3 May and at the time of the overpass on 7 May, was what amounts to a Category 4 storm. In doing so, it became the strongest May Southern Hemisphere TC on record.
Cyclone Ernie William Straka III
9-Apr-17 - At ~1846Z, during the time Ernie was weakening from a Cyclone to a Tropical Storm. The center circulation was hidden in the IR by high level clouds. However, cirrus is optically thick at IR wavelengths, but optically thin at VIS wavelengths, which means the moonlight reflects off low-level liquid clouds, allowing for the (slightly) exposed low level circulaon is visible only in the DNB imagery.
NCC image in AWIPS-II Don Hillger; Jorel Torres
7-Apr-17 - NCC image in AWIPS-II displaying the synoptic-scale storm over the western part of the US at 0935 UTC, 7 April 2017. In this case, NCC shows the location of the storm, recognizes clouds and snow via reflected moonlight, senses the emitted city lights, and highlight the gas flares in western North Dakota. In the top-right hand corner the moon percent visibility and moon elevation angle are provided where a positive moon elevation angle implies that the moon is above the horizon, which in turn, provides crisp, distinct satellite imagery.
Image of the Month: Tropical Cyclone Enawo Don Hillger; Torres Jorel
6-Mar-17 - A DNB image of Tropical Cyclone Enawo located just northeast of Madagascar. The image was taken at 2146Z, 6 March 2017. The moon percent visibility is 67%, and the moon elevation angle is 8.5°.
Image of the Month: Louisiana Tornado Outbreak Don Hillger; Dan Lindsey
9-Feb-17 - This VIIRS infrared image shows active thunderstorms across the Gulf Coast region of the U.S. from the afternoon of 7 Feb. 2017. Multiple tornado, large hail, and damaging wind reports were associated with these storms. The 375-m resolution provides a very detailed view of the cloud-top structure, highlighting features such as overshooting tops and enhanced-V's. The image is a color-enhanced VIIRS band I5 image at 375-m.
Solar Eclipse Seen from SNPP - Suomi NPP
passed directly over the solar eclipse path of totality as it
crossed the southeastern United States, producing interesting and
beautiful images via VIIRS, CrIS, and OMPS.
STAR JPSS 2017 Annual Science Team Meeting.
14-18 August 2017, STAR JPSS successfully held its fourth Annual Science Team Meeting at NCWCP.
Scientists from NOAA, NASA, Universities, and industries attended the meeting. (slides to be posted soon)

Message from the Program Manager:August was a very eventful month for STAR JPSS. The program held a successful STAR JPSS Annual Meeting, allowing team members to come together for important face to face meetings reviewing the progress and planning for the future of the program. Team members also participated in the SPIE OC+D conference and CALCON. In late August the teams were able to showcase Suomi NPP data by mapping the effects of the Great American Eclipse and the torrential rainfall in the wake of Hurricane Harvey.
