Looks like sunspot 720 is getting some attitude:

SPACE WEATHER ADVISORY BULLETIN #05-1
2005 January 14 at 03:51 p.m. MST (2005 January 14 2251 UTC)

**** RAPIDLY GROWING SUNSPOT REGION ****

On 10 January, a new sunspot group emerged and was assigned NOAA Region
number 720. This sunspot group has grown rapidly and currently has an
area of 1540 millionths of the size of the Solar disk (about 18 times
the size of the Earth). So far this region has only produced minor
flare activity (R1). However, its growth and complexity suggest that it
is capable of moderate to strong levels of flare activity (R2 to R3
levels) during the next 7 days. .

These types of flares lead to HF radio blackouts. The effects range from
minor degradation of HF communication (R1), up to wide area blackouts
on the daylit side of the earth for about an hour (R3).

Data used to provide space weather services are contributed by NOAA,
USAF, NASA, NSF, USGS, the International Space Environment Services
and other observatories, universities, and institutions. For more
information, including email services, see SEC's Space Weather
Advisories Web site http://sec.noaa.gov/advisories or (303) 497-5127.

Did you see those pictures of Titan on Space.com?

No, not yet. Just the one I linked yesterday. Think I'll go take a look.

 

[linuxgeek]

interesting. Wonder when they will release some in color--presuming they have a color camera on the probe.

Funny how it looks sort of like Mars.

hmmmm.. does sorta. I'm sure that will make for interesting conspiracy theories...

 

[Rhys]

Yeah considering that the Martian rovers mysteriously got dusted off and are still sending images.

 

[linuxgeek]

They have lasted a lot longer than expected. The best way to get more budget money is to make a project look like a success.

hmmmmm...

Looks like a coastline

 

[linuxgeek]

They were expecting liquid if I recall correctly. Believe liquid methane.

 

[linuxgeek]

Other neat thing on the ESA page. They have captures of wind sounds the probe has been sending back.

e: looks like the wind sound so far is primarily from when it was decending.

 

[linuxgeek]

Guess they did send a color capable camera:

does this mean the Northern Lights will be seen more to the south for a while?

 

[linuxgeek]

does this mean the Northern Lights will be seen more to the south for a while?

Doesn't seem so, this is X-ray emissions. So far no coronal matter ejected. There was one X1 flare from Sunspot 720. Rest have been M-class.

Looks like there will be alittle more arora activity expected for tomorrow, but still fairly high north.

and it'll be to fucking cold to go out and view... i bet

this figures. I say there haven't been any CMEs and what email shows up a little over an hour later:

Space Weather News for January 16, 2005
http://spaceweather.com

Two coronal mass ejections (CMEs) are heading toward Earth and they could spark strong geomagnetic storms when they arrive on January 16th-17th. Sky watchers should be alert for auroras. The CMEs were blasted into space by M8- and X2-class explosions above giant sunspot 720 on Jan. 15th.
