Lunar solar wind absorption…not entirely passive or evenly distributed

Unexpected activity on the Moon. The article says that this will have implications on the amount of surface water at various locations. Charles Lue holds a lunar globe showing the reflection of solar wind from magnetic fields of the lunar crust. The strongest reflection takes place in the areas marked in red on the lunar …

Sun’s circular filament eruption

So far, it’s unclear if the CME is on a path toward Earth, but the video is pretty cool.

I gotcher Space Weather resources right here

Er…Actually commenter Vic Moberg (MUOS PM support, former co-worker, and regular reader) provides a whole host of space weather resources as a comment to my post 156 years ago today. I quote the comment in its entirety: For those with a general interest in space weather, NOAA’s Space Weather Prediction Center maintains an “enthusiasts” dashboard …

156 years ago today

Since SpaceWeather.com is kinda squirrelly with links and all, I’ll just quote the entire article from their front page:   156 YEARS AGO, A GEOMAGNETIC MEGA-STORM: On Sept. 2nd, a billion-ton coronal mass ejection (CME) slammed into Earth’s magnetic field. Campers in the Rocky Mountains woke up in the middle of the night, thinking that …

Sunspot crash continues

Nighty-night, Mr. Sun. Looking forward to another mini-Ice Age like from 1300 to about 1850. Bundle up, everybody!

New Horizons…is there nothing it can’t do?

New Horizons Sampling ‘Space Weather’ on Approach to Pluto. Because the Mr. Sun is as inactive as ever during the Space Age, they hope that New Horizons will detect the boundary between Pluto’s atmosphere and the solar wind many planet radii away. As it is, New Horizons is already returning valuable data on solar winds …

Rhut rho…possible major CME heading our way

Per SpaceWeather.com/a>, an Earth-direct X2 solar flare erupted about 9:22am this morning. HF comms have been over the Americas: Meanwhile, natural radio emissions from the sun suggest that a CME might be emerging from the blast site at speeds exceeding 1,400 km/s (3.1 million mph). Stay tuned for updates. Yowza!

NASA SDO’s Fifth Anniversary video

The Solar Dynamics Observatory recently celebrated its 5th year in orbit, and NASA produced a pretty cool video of 5 years of Sun observations: Seeing the Sun in a time-lapse video like this really makes some things stand out that I either didn’t know or didn’t get until looking at it. Sunspots occur as within …

3rd attempt: Live-blogging SpaceX’s DSCOVR launch and booster recovery

DSCOVR launch trajectory

Live-blogging from work (without the big screen), so hopefully this will work out OK. All times Pacific. Finally: Rocket soft landed in the ocean within 10m of target & nicely vertical! High probability of good droneship landing in non-stormy weather. — Elon Musk (@elonmusk) February 11, 2015 1544: NASA-TV is shutting down…so I will too. …

2nd Attempt: Live-blogging SpaceX’s DSCOVR launch

Ok….The second time’s the charm, right? All times Pacific. The instantaneous launch window occurs at 3:03:23pm tomorrow. See you about an hour before then. 1451: Yep, the last weather balloon still shows High Level Winds. Mission is scrubbed for today. DANG IT! 1448: The penultimate balloon still shows high upper level winds. High level winds …

Big day for SpaceX today

Not only will they launch DSCOVR at 3:05pm Pacific and attempt to recover the first stage booster (have I mentioned that I’m live-blogging the event here starting at around 2:15pm?), but Dragon will complete its CRS-5 mission with a return from the ISS, with splashdown at 4:44pm. I may end up live-blogging both. My daughter …

Reminder: Live-blogging SpaceX’s DSCOVR launch and booster recovery (UPDATED)

It appears to be a slow news day, at least until 3:07pm Pacific when the DSCOVR launch will take center stage. Our live-blogging will start around 2pm, so we’ll see you then. Update: #DSCOVR update: Weather unfavorable today, so the next launch attempt will be Tuesday, Feb. 10 at 6:05 pm EST. pic.twitter.com/D0lR03gulG — NOAA …

Live-blogging of SpaceX’s DSCOVR launch and first stage booster recovery

All time Pacific local time. OK, I’m shutting down. Tune in tomorrow — I’ll be here live-blogging the launch through booster recovery. If the launch is rescheduled for tomorrow, the launch time would be 3:07pm California time. Ah…per Mr. Musk: Air Force tracking radar went down. Launch postponed to same time tomorrow. — Elon Musk …

SpaceX to attempt to land booster on ASDS on next launch

Which will be 31 Jan with the launch of the DSCOVR satellite. And yes, I’ll be live-blogging. DSCOVR will measure solar wind and monitor space weather at the L1 Earth-Sun point.

Effects of an M5 solar flare

Over at SpaceWeather.com, they report an M5-class solar flare erupted early this morning and struck the Earth with a pulse of ionized UV radiation. NOAA recorded the hit, which disrupted HF comms briefly when it hit: It’s unclear at this time if a CME erupted as well, but if so, it would likely miss the …

Yowza — looks like we just missed a CME event

I saw via SpaceWeather.com that an X-class eruption occured back on the 20th. The X-rays were directed right at Earth and it disrupted HF comms for hours in the southern hemisphere. The resulting CME, though, was directed much further south and if it hit Earth, it would only be a slight glancing blow. According to …

We definitely dodged a bullet in 2012

did I say “bullet”? I meant CME: To be hit by a CME of such magnitude…it’d possibly be a show stopper.

Solar sunspot activity still ramping down as predicted

Though November provided a small uptick. The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May …

Hold your breath…

Largest sunspot in 20 years facing planet Earth. Lots of flares so far that have temporarily disrupted communications planet-wide, but no Coronal Mass Ejections so far. It if does launch one toward Earth, batten down the hatches!!

You learn something new every day

Here’s an article about a satellite maneuvering to avoid some space debris, a topic about which I know an awful lot. My general take is that there are a lot of alarmists out there, and while it is a subject that bears watching, we’re not close to a scenario like “Gravity” occurring. By looking at …
