M2.4 solar flare, DSCOVR launch countdown

Solar activity increased to moderate levels thanks to sunspot region 2282. It produced an M2.4 solar flare that peaked yesterday at 23:35 UTC. The solar flare was long in duration and highly eruptive. A coronal mass ejection was launched but SOHO/LASCO imagery is still incomplete so it is unsure if there is an earth-directed component. An earth-directed component is however unlikely when we consider that the flare occured close to the east-limb.

ALERT: Type II Radio Emission
Begin Time: 2015 Feb 09 2323 UTC
Estimated Velocity: 1190 km/s
ALERT: Type IV Radio Emission
Begin Time: 2015 Feb 09 2335 UTC

The image below shows the latest available frame from the SOHO/LASCO coronagraph. The beginning of a bright coronal mass ejection can be seen but there is no way to tell if there is an earth-directed component. As mentioned before, an earth-directed component is unlikely but should other evidence contradict this conclusion then we will be sure to let you know.

DSCOVR launch countdown

It is launch day...! Hopefully! The Deep Space Climate Observatory (DSCOVR) mission is now scheduled to launch today at 23:05 UTC from Cape Canaveral, Florida on a SpaceX Falcon 9 rocket. NOAA reports that there is a 70 percent chance of favorable weather conditions today but should anything go wrong prior to the launch, there is a backup launch opportunity tomorrow at 23:03 UTC. The launch can be followed live on NASA TV. Their coverage will begin at 22:00 UTC.

Are you wondering why the DSCOVR mission will be so important for space weather enthusiasts or do you just want to know more about the DSCOVR mission? Read our news article from Saturday!

Any mentioned solar flare in this article has a scaling factor applied by the Space Weather Prediction Center (SWPC), the reported solar flares are 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.
