A “Blood Moon” total lunar eclipse occurred between 09:15 UTC and 12:34 UTC on 08 October 2014. One effect of this eclipse can be seen in a comparison of nighttime “during eclipse” and “after eclipse” Suomi NPP VIIRS 0.7 µm Day/Night Band images (above). The 11:33 UTC “during eclipse” Day/Night... Read More

Beginning shortly before 00 UTC on 07 October 2014, Typhoon Vongfong began a period of rapid intensification, as shown on a plot of the Advanced Dvorak Technique (ADT) intensity estimate (above). The peak ADT intensity late in the day was 146 knots. On the other... Read More

The Suomi NPP VIIRS image toggle, above, from the pre-dawn hours (3:42 am local time) on 6 October 2014 shows a 0.7 µm Day/Night Band image and an 11.45 µm Infrared image, along with observations of postive and negative lightning strikes. With ample illumination by moonlight, the “visible image at night” Day/Night Band image highlighted areas of convective overshooting tops, but also included... Read More
