The second largest geomagnetic storm on record has allowed people in mid-latitudes to see the aurora borealis and could possibly make for outstanding aurora viewing over Alaska through Saturday, November 22.
Another powerful solar flare has reached Earth on the heels of an enormous flare, giving Alaskans a great chance for aurora viewing in the next few nights. The most recent solar flare exploded from the surface of the sun at about 11:40 a.m. Alaska time, October 29, and researchers at the UAF Geophysical Institute say it arrived at Earth at about noon Alaska time, October 30.
A powerful solar flare that resulted in active aurora displays Tuesday night and Wednesday morning may also trigger outstanding displays on Wednesday evening. “If the skies clear up tonight, it’s going to be a whopping good aurora,” said Charles Deehr, a professor emeritus and aurora forecaster at the University of Alaska Fairbanks Geophysical Institute.
NASA Administrator Honorable Sean O’Keefe made a special trip to Poker Flat Research Range Thursday to visit the NASA supported facility. O’Keefe reports directly to the President of the United States as the leader of the NASA team and manager of the agency’s resources. NASA General Counsel Paul Pastorek accompanied O’Keefe and the two were given an extensive tour of the facility by Range Manager Greg Walker, and Associate Director Hans Nielsen.
Poker Flat Research Range retrieved remnants from a rocket Saturday that had been launched March 27 as part of a four-rocket experiment to study winds in the upper atmosphere. The retrieved rocket did not thrust properly during its flight, causing it to fall short of its predicted altitude and land in a different part of the designated impact area than expected. It was found 5.8 miles north of the range in the special land use designated area for rocket booster impact. NASA is interested in studying the rocket’s remains to better understand the cause of the thrust failure.
A series of four rockets were launched in rapid succession from Poker Flat Research Range at 3:09, 3:10, 3:12 and 3:13 a.m. Thursday as part of a mission to help scientists view wind associated with an aurora from cameras on the ground.
Two rockets were successfully launched from Poker Flat Research Range at 12:50 and 1:09 a.m. Tuesday as part of a UAF Geophysical Institute-lead experiment to study winds in the upper atmosphere related to the aurora.
Poker Flat Research Range has extended its rocket season with a third launch window. The addition will give two rocket missions designed to study the aurora more time to perform their experiments. From March 19 through April 7, scientists will look for the optimal weather and aurora conditions to launch six rockets.
Live audio coverage of Poker Flat Research Range’s rocket launch countdown is now available to the public via the Internet. For the remainder of the 2003 launch season, near real-time audio coverage including broadcasts of each of the six remaining launches can be accessed by visiting http://carrot.pfrr.alaska.edu/poker.
Four rockets are scheduled to launch in rapid succession from Poker Flat Research Range when the weather is clear and calm and aurora conditions are suitable between February 22 and March 10 as part of a mission to study high-latitude heating during an auroral substorm event. Two of the rockets in the JOULE experiment each will carry instruments to measure light and small-scale electrical currents in the upper atmosphere.
