Finally – East coast may see colorful clouds from NASA Wallops Sounding Rocket Test On Fathers Day

Northern Lights Now – After several scrubs, NASA looks set to successfully launch a Terrier Improved Malemute sounding rockets on Father’s Day, Sunday evening June 18, between 9:04 and 9:20 pm. The mission will deploy gasses into the ionosphere that hopefully will be visible as different colored high altitude clouds. Scientists are hoping to measure and track gas particle movements within these clouds. It is expected that the experiment will test some aurora imaging technologies, and the data may help use get a better understanding of Aurora. You may be able to see this launch if you live in the shaded areas in the map below!

NASA scientists need it to be clear at either the launch site or nearby Duck, North Carolina to study the induced clouds. Several recent scrubs have been the result of skies that were too cloudy or hazy to be able to see the experiment. Another scrub was the result of boats in the “danger zone,” the area where the sounding rocket is expected to land in the ocean at the end of it’s task.

So far, it’s looking like the weather could be touch and go. The forecast calls for a chance of thunderstorms. An ill-timed thunderstorm arrival could make for yet another scrub. If the storms roll through at 6:00 and it clears out – there’s a good chance the launch will happen this time as long as boaters stay out of the danger zone.

What will I see During the the DC launch and test?

Viewers from New York City South to Greenville, North Carolina have a chance to see the rocket itself and the induced clouds. It is hard to know what the clouds will look like, but reports are that they may look similar to aurora or noctilucent clouds. However they look, it may be possible to see them with your bare eyes. The timing of the launch coincides with nautical twilight, so it will be after sunset, but there will still be a little light in the air.

To increase your odds of seeing this show, bring your digital camera and a tripod. Photographing these clouds will be similar to photographing aurora – and a great chance to practice! You don’t need a high end camera, but you will need to be able to manually set Aperture, ISO and exposure duration. Photograph the clouds with long exposures (1-5 seconds) and higher ISO (800-3200). Set your focus to infinity and consider a delay on the camera between hitting the trigger and when the image start so the camera can settle. If you get a great image, be sure to share it on NLN’s Twitter feed

What is a Sounding Rocket?

Sounding rockets are small instrument-carrying rockets designed to cost effectively reach altitudes between 50 and 1500 km. This is between the area that weather balloons can reach and where it is coast effective to send a satellite. They are frequently used in research because a mission can be designed and completed in months to years compared to the years it may take to get an experiment aboard a satellite mission. NASA has a terrific quick 5 minute video talking about sounding rockets and an experiment they were used for to study aurora

Update #2: Mid-October Aurora Reached G2 storming, G3 predicted

Northern Lights Now – The predicted G1, then upgraded to G2, aurora predicted for October 13-15 is meeting and exceeding expectations. KP values recorded in 3-hour increments by the airforce and SWPC were registering between G1 and G2 for much of the day. KP predictions from the Wing-KP model ranged from 4.67 to 7.67 from Noon GMT through Midnight GMT. SWPC has upgraded the watch level on the 14th to G3. Storming will likely only reach that level if the storm continues to intensify – and there have been some hints that it is starting to wane. Here is the chart showing today’s recorded geomagnetic activity:

At the peak of today’s storm the Bz had rotated powerfully to the south, registering as much as -20 nT. This is some of the strongest negative orientation of the Bz since the Saint Patrick’s day storm of 2015. In addition to being strongly south, the field maintained that orientation for a long time. As of this writing, the Bz had been negative for almost 20 hours. This is the longest duration negative Bz since NLN started producing this graphic that shows the duration certain important thresholds for aurora have been exceeded:

With a storm this strong, we’d normally expect to see many wonderful aurora pictures rolling in from our readers and aurora hunters. However, there were a lot of clouds in the normal viewing locations. In NLN’s HQ city of Burlington Vt it was raining most of the day and is cloudy this evening. The Moon is also nearly full, currently at 94% visible, and is washing out the aurora for people who have clear skies. That isn’t stopping photographers, and there are a few beautiful pictures rolling in. Here are a few. Please tag @northlightalert in your photos if you’d like to have them featured in the NLN blog!

December 2015 Aurora Among Best of Solar Cycle 24

Northern Lights Now – A solar storm resulting from a pair of CMEs arrived at Earth on December 19, 2015 and induced 30 hours of G1-G2 aurora activity. It proved to be one of the strongest geomagnetic storms of solar cycle 24. Aurora hunters around the world were able to capture stunning photographs of green, red, pink, and purple swirling through the sky. NLN will be writing a complete recap post, but here is a teaser of amazing tweets that has been in the NLN feed over the last two days.
