Explosion Rips Open a Canyon of Fire on the Sun

 

Canyon of fireThe sun really has been acting up lately. In October, solar activity jumped to its highest level in two years, with a large uptick in the number of sunspots and a concomitant rise in flares and giant eruptions of plasma from the sun’s surface.

A filament of plasma 25 times bigger than the Earth exploded from the sun recently, leaving behind this temporary burning gash in the solar corona.

The image above shows the immediate aftermath of one such eruption. Captured by the Solar Dynamics Observatory satellite, or SDO, it shows what NASA describes as a “canyon of fire” left behind after a 200,000 mile long filament exploded outward through the sun’s atmosphere (Corona).

The red images shown in the movies below help highlight plasma at temperatures of 90,000° F and are good for observing filaments as they form and erupt. The yellow images, showing temperatures at 1,000,000° F, are useful for observing material coursing along the sun’s magnetic field lines, seen in the movie as an arcade of loops across the area of the eruption. The browner images at the beginning of the movie show material at temperatures of 1,800,000° F, and it is here where the canyon of fire imagery is most obvious.

Comet Ison - Naked Eye Object this week?

comet ison1Observers around the world are reporting that Comet ISON brightened sharply last night and is now at the threshold of naked-eye visibility. By some reports, ISON surged in brightness by approximately 2 magnitudes over last 24 hours and is now brighter than comet Lovejoy.

If this trend continues, it will be a faint but easy naked-eye object by the end of the week, SpaceWeather reports.

The sudden uptick in brightness could be caused by a fresh vein of ice opening up in the comet's nucleus. Rapid vaporization of ice by solar heat is a sure way to boost a comet's visibility. 

ISON's brush with the Sun on November 28th is very near and many more of these brightening events might happen but all three scenarios for ISON are still open. The first possible scenario is fizzle - ISON evaporates under intense tidal forces and solar radiation. The second scenario is break-up - ISON breaks into smaller chunks.

The third scenario is what everybody hopes will happen - sizzle - ISON survives its brush with the Sun and emerges so bright it becomes visible on Earth in daylight.

The Big Picture....

BigPix....about DX operating.

You may find this video interesting. It was made by Rick K6VVA ''The Locust'' and enlightens us how we should operate and what we should strive to do with our operating to make it as effiencient as possible.

It also highlights how DXpeditions should operate and how their operators can make life a lot easier for themselves by adopting minor changes to their operating practices.

Clich the video to see the presentation. Thanks Rick !

 

 

 

 

Worldwide Iron Ham Contest 2013

adxcThe WORLD WIDE IRON HAM CONTEST is a unique world-wide contest intended to promote the multi-mode skill of the ham contest community in one single 24-hour period competition.

The GADX Araucaria Dx Group together with the majority of the Brazilian Contest and DX Clubs, based upon the success of the IRON MAN and some other multi-sports competitions, are sponsoring a different contest alternative where the competitors must use several alternatives to test their skills in different ham radio modes on all bands around the clock for 24 hours.

DX Code of Conduct ethics

 

dccAre you aware of the DX Code of Conduct?

 

This DXpeditioners’ Code is to help maximize the fun for all participants. As the DX operator, you play a critical role in pileups: you are "in charge”. Dealing with an unruly pileup of discourteous operators who have forgotten about ethical behavior is NOT fun. So it makes sense to plan and train ahead of time on how best to deal with the situation

 

Good operators at the DX end and courteous behavior at the other end of the QSO can greatly increase the total number of QSOs logged. It has been demonstrated that pileups can be kept reasonably under control if the DX operator follows certain ‘rules’. Luckily, some top operators have given us the benefit of their experience. Please peruse these suggestions on this link and bear it in mind when calling the many Dxpeditions that are currently active.

Extended stay at MC0SHL

M0OXO MC0SHL1Well the band conditions have been so good that we have decided to stay at the Clubhouse
in GW for a few more days, intending to travel home maybe Monday.

Conditions on 12 and 10m here having been unreal. Tim M0URX and I have logged well over 1000 q's
in the sporadic operating over the last few days and probably 900 of those have been into NA. WP 20131019 011


We almost worked all States on each band but missed out on HI and the two Alaskan stations we worked turned out to be in a different area than the Callsign showed ;-( When 12m actually did close around 2030utc we took time out for a few beers with Stuie VK8NSB joining in the fun on SKYPE.

Ah well, there is always today....and tomorrow.....

Logs are already uploaded to LOTW (thanks Chris G1VDP) so the many people that thanked us for the new slot on 12 & 10 should already have it confirmed.

****had another good run on 40m this afternoon/evening and log for this latest visit now ended with 1740 qso's logged. Thanks to all that worked us this weekend.... I will be back as MC0SHL in a few weeks!

 

Typhoon Francisco targets Japan next week

franciscoTyphoon Francisco continues to become better organized in Northwestern Pacific waters as it spins southwest of Guam.

The system barely missed the island of Guam twice on its southwestern track before it changed direction to the northeast. Francisco has developed in a similar area to where former Typhoon Wipha formed last week. Francisco is now located southwest of the island and is moving northwest with maximum sustained winds of 96 mph.

The Joint Typhoon Warning Center forecast has the storm moving north-northwest towards Japan over the next week.

 

 

 

Comet ISON expected to survive close Sun encounter

IsonNew studies released at the American Astronomical Society’s 45th Annual Division for Planetary Sciences meeting in Denver, Colorado suggests that Comet ISON could make it through its close perihelion passage near the Sun.

The first criterion for ISON to survive perihelion is its nucleus size. Comet nuclei smaller than 200 meters in diameter, with an average density or lower typically do not survive a close passage to the Sun. Observations from the Hubble Space Telescope, as well as smaller telescopes, suggest that ISON is between 1 and 4 kilometers across..

ISON may be just big and dense enough not to be vaporized and to survive its close encounter with the Sun. So it looks like ISON appears likely to survive the combination of mass loss due to sublimation and tidal disruption for most plausible scenarios.

ISON will pass inside the Roche limit of the Sun, which is a distance of 2.4 million kilometers with temperatures approaching 5,000 degrees Fahrenheit on closest approach. Comet ISON is expected to be the most active and put on its best showing post-perihelion - if it survives.

 

MC0SHL on air this weekend

Bangladesh 2013

image2Great  news from the Mediterraneo Dx Club International Team. The leader Antonio, IZ8CCW and co-leader Gabriele, I2VGW are happy to announce to the DX community that after many months of hard work and with the great help of a local friend, Manjur, they were able to obtain a wonderful set of twin call signs that  will accompany the team during their new DXpedition to Bangladesh:  S21ZBC AND S21ZBB.

As a matter of fact, they are going to use the first one ( S21ZBC) with the DXpedition starting November 16th and ending November 22nd. Then they’ll shift to the other call (S21ZBB) that they’ll begin using November 23rd for the CQ WW CW CONTEST  week-end and for those remaining days until they pack up and leave the country.

Iceland - 1000 Earthquakes in 6 days

iceland earthquake swarm oct 1 2013An intense earthquake swarm has been going on offshore North Iceland, 10 km NW of Gjögurtá, since September 25, 2013. This morning, 2 earthquakes reaching magnitude 3 and 3.2 occurred at 06:14 and 07:41 UTC. Roughly 1 000 earthquakes have been recorded by Icelandic Meteorological Office in last 6 days.

The depths of the quakes vary from about 15 km depth (crust-mantle boundary) to near surface. The area is located on an active fault line related to rifting, and a possible cause of the earthquake swarm could be a magmatic intrusion at Tjörnes Fracture Zone volcano.

Eruption of Jebel Zubair volcano

 

jebel zubair eruption sep 28 2013 lrgA new submarine eruption started on September 28, 2013 NW of the island Jebel Zubair in the Red Sea. The ongoing eruption is SW of the 2011-12 eruption which created a new volcanic island there.

Satellite image from January 7, 2012, suggested that the eruption has risen nearly completely above water. A plume of steam, other volcanic gases, and ash spewed from a distinct cone. The land surrounding the vent has grown, and was about 530 by 710 meters (1 700 by 2 300 feet) across. Once above water, past eruptions in the Zubair Islands were primarily effusive, with relatively runny lava forming thin lava flows. In contrast to the fragmented rock that forms when lava interacts directly with water, lava that solidifies on land is tough, so this new island is likely to stick around.

 

The 5-km-long Jebel Zubair Island is the largest of a group of 10 small islands and submerged shoals that rise from a shallow platform in the Red Sea rift.

This latest phase of activity occurred on the morphologically youngest islands of Zubair, Centre Peak, Saba, and Haycock. Historical explosive activity was reported from Saddle Island in the 19th century. Spatter cones and pyroclastic cones were erupted along fissures that form the low spine of Zubair Island.
