Hugh M Eye User ID: 7181448 United States 12/15/2011 05:43 PM Report Abusive Post Report Copyright Violation | Latest "Birthday Comet" update from Sungrazer.mil: 2050UT: Well if there was ever any doubt as to how bright Comet Lovejoy would get, our question is now answered: ridiculously bright, I believe is the scientific term! As reported by SpaceWeather.com, "Matthew Knight of the Lowell Observatory and JHU-APL reports: "As of 16:30 UT on Dec. 15th, Comet Lovejoy has reached magnitude -3, possibly brighter. It is starting to saturate SOHO images even with narrow filters and shorter than normal exposure times."". When we say "saturation", we mean that the individual pixels in the CCD camera are obtaining too much light and are getting overexposed. The CCDs (Charge-Coupled Device) pixels are like tiny buckets that collect light instead of water, and just like water bucket, when they receive too much light they overflow. But due to the way the CCDs are manufactured, the pixels can only overflow horizontally into their neighboring pixels, and thus when we get a bright object in the field of view, we see the horizontal bars you see dominating the coma of Comet Lovejoy in the LASCO data. To overcome this we do try to reduce our exposure time, and this will work to an extent. But it seems that Lovejoy is just too overwhelmingly bright and consequently we are simply unable to get short enough exposure times to prevent saturation, even in our narrow-band filters. This makes it hard to get completely accurate estimates of the brightness of the comet. But where we have "lost" the LASCO observations, we have gained the SECCHI COR2 images! Once again my incessant nagging of my coworker pushed her into playing back the COR2 images we took earlier today, and so the result is a nice big set of data, which I have lovingly wrapped up for you all into a big 147MB Zip file! But of course you don't want to have to fight with FITS files when you can have lovely pre-processed PNG images sitting in a slightly smaller 30MB Zip file. But then who wants to make their own movie when you can download a lovely, if somewhat huge, 188MB QuickTime Movie or a somewhat more portable 47MB QuickTime Movie? And for the ultra-impatient among you, here's the most recent, high-res, fully processed STEREO/SECCHI COR2-A image of Comet Lovejoy. And look! No saturation!! [Please, do yourself the favor of right-clicking those links and saving the files locally. Your web browser will thank you later.] Aren't I nice?! Oh, and within an hour we will have contact again with SOHO. When we get those images, I expect to see C2 dominated by a huge streak, and the comet's head probably just disappearing behind the central occulting disk. They should be very striking images!

No one knows if comet will hit or just graze the sun's atmosphere. There's even a small possibilty that will survive perihelion-though it will most likely break apart. [link to sdo.gsfc.nasa.gov] |

Rain-Man User ID: 7183013 Bosnia and Herzegovina 12/15/2011 06:45 PM Report Abusive Post Report Copyright Violation | Definitely it's going to hit the Sun, more of 70 % of possibility for strong CME on opposite side of impact .. Question is how match hi meltdown at this moment and what composition this comet is made .. It's from Kreutz-group comets, so very possibility will have same influence on Sun like last bigger one from Kreutz-group comet ..

Then at 7:30 (00:30 utc) spacecraft will go back to normal observing. So we should have about one full hour of SDO images-00:01UTC-01:00UTC. Thirty minute lag time from Sol to internet. Ten minute countdown starts....NOW! |
