Solar Forecast: Extremely Hot with a Chance of Rain?

Check out this amazing NASA video of a solar flare that occurred in July 2012. Accompanying the flare was a phenomenon known as coronal rain. Coronal rain is actually hot plasma, which cools and condenses in the strong magnetic fields produced by solar flares. The plasma is eventually pulled back toward the surface of the sun. The magnetic fields help create a visual illusion that allows the plasma to appear in patterns similar to rain, fountains, or even fireworks. -Joe

Ten years ago…

…I lived about a thousand miles away from home, forecasting the weather for East Texas on KLTV. February 1, 2003 became a day I will never forget.

It was a Saturday, a day I was off of work. My pup, Theo, was just about three years old and slept every night on the foot of my bed. He was a deep sleeper (as was I) but awoke abruptly that morning. Usually, if someone knocked on the door, he ran to the door to announce the arrival of a visitor. This time, he stood on top of the bed barking loudly, for no apparent reason. I calmed him down but within a minute there was a loud knocking on my front door. I scratched my head, threw on some shorts and opened the door. My next door neighbor Harrison, out of breath, was describing the sound of an explosion. We looked in all different directions in the sky and down Grande Boulevard, expecting to see a plume of smoke from a car wreck or something. In my calmer state, I assured him everything was alright and he needed to get back to the morning routine (of sleep). We were both in our 20s and 8:30 in the morning on a Saturday was not the time to be bushy-tailed and bright-eyed.

I got back into my warm bed and within another minute my phone rang. It was my mom calling from Illinois. Her first words were “Eric, are you watching CNN?” My first instinct was 9/11 as we both watched on TV what was happening to our country while talking on the phone. I went into the living room, turned on the TV to find the banner “Breaking News: Communication with Columbia Lost.” It took me a while to grasp the severity of the situation. When the news anchors showed the flight path from Texas to the landing site in Florida, I began to piece the events of my morning together.

A vivid sight in the sky was captured by a Tyler, Texas doctor February 1, 2003.

The loud “explosion” my neighbor heard (and that woke Theo) was the sound of the Space Shuttle Disaster. I told my mom I would call her back later and then ran next door to tell Harrison (now back in bed) what had happened. He immediately grabbed his camera and we jumped into my car. My first instinct was that of the shuttle sitting nose-first into a field nearby. At that time, we didn’t know it broke up on entry. I thought there might have been a mechanical failure that caused it to literally crash.

As we exited the gates of my apartment community, I remember the wail of emergency vehicles in all different directions. It was surreal as I had never heard that before. We drove southwest on Texas 155 toward Palestine as that’s where CNN said some of the crash debris had been located.

Because it was a February Saturday in East Texas, we noticed there were fires burning in fields as we left town. It was nothing out of the ordinary as farmers and ranchers typically did that sort of thing on weekends. Later in the day we found out the fires were that of burning debris that had been strewn over hundreds of square miles of East Texas.

I remember seeing pieces of twisted metal on the shoulders of Texas 155. Again, I didn’t think twice about it since it was a fairly busy highway and trucks lose their loads a lot and cars have fender-benders occasionally. Later that day, it became obvious to me that the debris was in fact from Columbia.

After being gone about 45 minutes, we decided we weren’t going to see anything and if there was something to see the authorities wouldn’t let us anywhere near it.

I called the KLTV newsroom to see if there was anything I could do but our assignment manager said that they were calling everyone in, except for the Meteorologists. I went back and watched the coverage for hours, not knowing what emotions I was supposed to feel. KLTV’s coverage lasted for days…literally, days. Our coverage revolved around Columbia as we became Ground Zero for our nation’s new tragedy. I remember how wonderfully the team came together. One of my dear friends Dana Dixon, a reporter for KLTV, was sent to Nacogdoches where NASA had set up a command post. She had the daunting task of reporting on the recognizable remains of the shuttle and its occupants. I remember she broke up a few times on the air as any true reporter sometimes does during significant events. She held it together day in and day out providing the latest information to me, our viewers, and the nation during national news cutins. That Saturday turned every employee of KLTV into a true journalist, all of which I was proud to work with. Heck! The TV station’s slogan was and still is “Proud of East Texas.”

Space Shuttle Columbia memorial at Arlington National Cemetery (Taken by 13News Anchor Eric Wilson two weeks ago)

I remember where I was during the Space Shuttle Challenger disaster and on 9/11 and felt many of the same emotions ten years ago today. Just yesterday, I read an article that NASA knew there could be problems on re-entry, due to broken heat shield tiles on Columbia’s wing. Because another Shuttle wasn’t ready to be launched and Columbia’s mission was far removed from the International Space Station, they could either notify the crew and keep them in space (rapidly losing oxygen) or try to bring them back to Earth. I believe NASA made the right decision not to communicate their fears to the crew. Instead of potentially dying in space, gasping the last available breaths of air, they died in a few seconds on re-entry as heroes…modern-day pioneers. The risks they took along with their final sacrifice should never be forgotten, whether it is the 10th anniversary or the 11th, or the 200th!

For me, I remember more from Saturday February 1, 2003 than I do six days ago. Maybe it’s because I wanted to be an astronaut when I was really young. But most likely it was because it hit so close to home.

The comet of the century?

As a kid, I vividly remember the awe and wonder surrounding Halley’s Comet which floated through the sky in 1986. I had posters, special commemorative Matchbox cars, and tons of magazines. The thought I would get to see a comet, not visible for another 75 years fueled that wonder.

Now, a new group of astronomers have discovered a comet that some say could be brighter than the moon! Here’s what ”Ison” looked like in September…barely noticeable! It’s still very far off, beyond the orbit of Jupiter. But by November 2013, it will be close enough to possibly become the brightest thing in the night sky!

Ison will pass 1.1 million miles from the sun’s surface. As it buzzes through, the comet’s chunks of rock and ice will be heated, reflecting the light from the sun. By late autumn, Ison will be viewable in the sky in both the Northern and Southern Hemispheres. There’s a chance Ison could break up and burn apart as it nears the sun, but if it doesn’t, it could illuminate our sky into January 2014.

If Ison wasn’t enough to spark your comet-interest, another comet called “2014 L4″ was discovered in 2011. It could light up the skies in March and April.

Geminid Meteor Shower peaks Thursday Night

VIEWING FORECAST:
Tonight: Mostly Clear. Lows around 30.
Thursday Night: Mostly Clear. Lows around 29.
Friday Night: Cloudy with Rain. Lows around 36.

Get ready for one of the most stunning displays of shooting stars of the year! According to NASA, the Geminid meteor shower this year lasts from Dec. 10-16, with Thursday night, Dec. 13, anticipated to be the peak time for viewing. There could be more than 50 meteors per hour. But get ready for even more per hour since there is debris left over from Comet Wirtanen which could add another 30-50 meteors per hour! That would be specatcular!

The Geminids are debris from an object called 3200 Phaethon. NASA said Phaethon was long thought to be an asteroid but is now classified as the rocky remnant of an extinct comet that lost its ice after too many close encounters with the sun.

In order to get your best glimpse of the Geminids, get out of the city, away from the lights. Give your eyes time to relax and get used to the dark sky. Then, look up. Most Geminids usually fall shortly after midnight, centered around 2am local time. The time holds true, no matter what time zone you’re in.

Enjoy! And be sure to let us know what you’re seeing! -Eric

It’s a Bird, It’s a Plane, It’s…….

If you have ever gazed up at the night sky and tried to envision distant planets in unexplored depths of space, tonight you will be able to catch a glimpse of one of those very planets. As the sun sets this evening, find the moon in the early night sky. You’ll find it in the north northeast and you also should notice something else just as bright. A slightly smaller, but equally impressive “star-like” body will be near the moon all night long. That apparent star is actually the planet Jupiter. The moon is over 1,500 times closer to the Earth than Jupiter is so it will appear to move throughout the night and Jupiter will remain stationary. It will be easily visible with the naked eye, however if you happen to own a telescope you are in luck. Through the weekend, especially on Sunday night, the rings and moons of Jupiter will be incredibly visible by telescopes and even binoculars. Check out the view that is out of this planet! -Greg

Northern Lights may be obscured by clouds

Here is a look at where the Northern Lights (or Aurora Borealis) may be seen tonight. Unfortunately, for most places, thick cloud cover may make it impossible to see. There are a few breaks in the cloud deck in the Prairie Provinces of Canada and Minnesota. The clearing in Minnesota is expected to move toward Northern Illinois late tonight. So while there is a fair amount of cloud cover now, look to the north during the predawn hours and you may see the ‘lights.’ And let us know on the 13 Weather Authority Facebook page.

And with heightened solar activity, there’s a chance we may see the Aurora show up on our maps Saturday night. (Unfortunately we are forecasting more clouds to be above our skyline then.) We shall see! -Eric

Out of This World

The 2012 election is now in the rear view mirror. Thousands upon thousands of absentee ballots were cast from all ends of the globe as people couldn’t make it back to the country to venture to their local polling place. Some of these votes can literally be out of this world. NASA allows astronauts that are current on mission in space to vote via electronic ballot. The votes are cast on a secure connection and sent straight to the voting headquarters. This process wasn’t used this year, but two astronauts currently on the International Space Station did cast votes before they left on their mission. Votes from space have been cast in the past –  talk about going to great lengths to exercise your democratic freedom! -Greg

2012 Orionid Meteor Shower

Skywatchers, get ready! This weekend will be the peak of the Orionid Meteor Shower. According to NASA, it will peak Sunday October 21st, very early in the morning. Each year at this time, the Earth passes through a stream of debris left over from Halley’s Comet. Brilliant, fast-moving shooting stars are observed at a rate of 25 per hour. And this year there will be an added treat: no moon! The moon often pollutes the dark sky with light, making many of the shooting stars very hard to see.

And when you see one, make a wish quickly! They will streak across the sky at 148,000 miles per hour!

GOES/NWA Satellite Info

The status of weather satellites has become an increasingly important issue over the past three weeks, and part of the NWA Annual Meeting was dedicated to discussing expectations of future satellite capabilities. Weather satellites have become a major issue because back on September 23 the satellite in charge of monitoring the entire east coast, and the Atlantic, GOES-13, went offline unexpectedly. At this time it is still unclear if the satellite can be repaired. GOES-13 was put into operation back in 2006 and was supposed to last at least a decade.. that doesn’t seem to be a reasonable goal anymore. As we speak, another satellite, GOES-14, is slowly moving toward the position of the inactive GOES-13 satellite in order to take its place and begin retrieving data from the East Coast. This won’t be a quick fix because GOES-14 will take the entire month of October to move to its new location.

That brings us back to the NWA conference and the topic of satellites. With the apparent need for satellite upgrades and maybe even new satellites all together, NOAA’s Satellite Division expressed some futures hopes and expectations for satellite operating capabilities. As of now there are 17 environmental satellites in use. NOAA wants to improve snapshot times by its satellites from once every 20 minutes to once every 5 minutes, and higher that rate to once every 30 seconds in storm events. This decreasing refresh rate would increase data into computer models which would increase the accuracy of forecasts. Faster satellite refresh times would lead meteorologists to have a much better picture of the story on the ground, and help us to better inform you of any incoming threats. -Greg

Harvest Moon

Be sure to look out into the sky, especially just after sunset!  The Harvest Moon, also known as the Blue Corn Moon among other names, will be out in full force Saturday night and Sunday night (September 29 & 30).  The Harvest Moon is a full moon that occurs near the time of the Autumnal Equinox (harvest time in the United States).  The equinox occurred this year on September 22, 2012.

 

The Harvest Moon is known for its distinct color, usually a red-ish / orange-ish tint, and large size.  The reason why the full moon looks that way is due in part to its low angle in the sky.  The low angle on the horizon allows all of the little dust particles in the atmosphere to scatter and reflect the moonlight.  The moon’s normal blue-ish tint is scattered in a way that the red-ish tint (which our eyes can’t normally discern) becomes most visible.
