I went out onto the courtyard this afternoon to try and photograph sunspotsbut had no luck since there was a thin overcast layer of cirrus clouds. Damsel noticed that there was an arc around the sun so I positioned myself underneath the big saguaro out front and took this image of the phenomenon.
The halo around the sun reminds me of some of the halos around the heads in medieval art works such as “Madonna y Bambino” and other halo-worthy holy figures that we saw in The Vatican, Rome and Florence, Italy a few years ago. Click on the image to enlarge.
There is a parade of sunspots crossing near the solar equator today. I went out this morning and captured the sunspots with my usual setup of the Canon SX-40 through the cheap little solar filter from Rainbow Symphony. Click on the image to enlarge.
AR 1974 is pointed directly at the Earth and could produce flares. AR 1975 and AR 1976 look to be more intense and will be pointed earthward in a day or so. This could mean auroras in the arctic, communications and electrical grid blackouts or enhanced radio communications as in Ham Radio. Or, it could mean nothing at all.
We have seen from the past that the presence of sunspots generally means warmer temperatures on earth while the absence of them for prolonged periods tend to bring cold periods called minima. Some examples are the Maunder Minimum, the Dalton Minimum and the 1900 Minimum. There was an unnamed minimum in the 1960’s that had Time and Newsweek predicting a new ice age. But, we know how the news media wants to bend things around to capitalize on sensationalism to sell copy, I guess. Or maybe to put forth a political agenda. I think we all know how the media operates these days.
Huge sunspot AR 1967 erupted with an M6 class solar flare a couple of days ago. It is not aimed directly at Earth, but scientists predict a 45 percent chance of auroras at high latitudes when the CME glances off the magnetosphere tomorrow. I photographed these two active sunspot regions around noon local time in Arizona. Solar north is up. Click on the image to enlarge.
There was a larger event in late December when the prediction for auroras was such that perhaps they could be seen at lower latitudes, but alas, nothing here at latitude 34. It is possible at this latitude (I have seen auroras in Southern California) so if we live long enough we may see them again here in our Arizona dark skies.
During my daily web browsing, I saw this note about today’s solar activity on SpaceWeather.com:
(ALMOST NO) CHANCE OF FLARES:
Two sunspots facing Earth (AR1934 and AR1936) have ‘beta-gamma’ magnetic fields that harbor energy for strong flares. Both sunspots have been quiet for days, however, and they show no signs of an imminent eruption. This has prompted NOAA forecasters to place low odds on flares today: a 25% chance of M-flares and a 1% chance X-flares.
I took the above image today of the sun and annotated it with sunspot numbers for those visible to my camera. Click on the image to enlarge.
This morning, I browsed my usual daily visits on the internet. When I got to the webpage at SpaceWeather.com, I noticed several sunspots were visible on the “Daily Sun” feature in the left sidebar. That made me have the urge to go out and capture an image of the sun over Arizona to see if I could resolve any of the sunspots. There were three distinct spots in my image, which I labeled, as seen on the right. The solar north pole is at about the ten o’clock point in the image I made. I didn’t bother to rotate the solar image to align the pole at the top as I sometimes do. Click on the image to enlarge.
I visited the SOHO Sunspot page to get the designation numbers of the sunspots in the photo, I noticed a link to a new feature called Helioviewer which purported to allow users anywhere make their own custom images and movies. After fooling with the website a bit, I made the video below to document the spots in my image. The motion starts about 24 hours before advancing to how the sun looked today. Solar north is up and the recording was made through a hydrogen alpha (or equivalent) filter. The bright spots are the location of the spots in my image above. See this screenshot from the Helioviewer site for reference.
This three-panel slideshow contains amateur photographs of some of the things we have seen in the sky over the last few days. The first and second panels show “sun dogs” and the last panel shows a circumhelical arc, all of which are rainbow-colored patches of refracted sunlight through ice crystals high in the Earth’s atmosphere. I used my hand to block out the direct sunlight in the last panel.
I read about this sunspot on SpaceWeather.com today. Seeing the article prompted me to get out the tripod and solar filter out and try to get a picture of my own. In the enlarged version of this image, you can see that I managed to capture the structure of this unusual-looking sunspot (inset). Click on the image to enlarge.
Around the world, amateur astronomers are snapping pictures of behemoth sunspot AR1734 as it crosses the solar disk. In Buffalo, New York, photographer Alan Friedman noticed something when he rotated his picture 90 degrees. “Sunspot 1734 has a definite owlish look!” “But who gives a hoot,” he continued, “this grand active region looks fantastic from every perspective.”
The owl could be poised to explode. Sunspot AR1734 has a ‘beta-gamma’ magnetic field that harbors energy for M-class solar flares, almost-certainly Earth-directed because the sunspot is facing our planet. NOAA forecasters estimate a 45% chance of M-flares on May 6th.
