Solar Eclipse: View from Tidore, Indonesia
Constantine: "It was an unbelievable spectacle with a huge prominence!"

Date: March 9, 2016
Constantine Emmanouilidi: Diamond Ring Vs. Prominence.

I'm still amazed by the gorgeous combination of the Baileys Beads with this extraordinary prominence just next to it. We were very lucky on this one! The image was made with the smaller telescope with 60mm aperture.

Constantine Emmanouilidi: The corona structures were magnificent during the totality. I really enjoyed the three minutes of totality. To me it was three minutes of pure calmness! And the spectrometer showed that the sun is still very active, more to follow soon.

Nikos Plexidas: Κωνσταντίνε, ευχαριστούμε για τις υπέροχες εικόνες που μας μεταφέρεις....

Εμείς εδώ μακριά έστω και κατ ελάχιστο παρακολουθήσαμε την έκλειψη από το διαδίκτυο και πήραμε μια μικρή γεύση από αυτό το μοναδικής ομορφιάς γεγονός!!!!

Thanks to Constantine Emmanouilidi, amazing capture.

Finally the wait is over and the processing of the data from the Total Solar Eclipse from last March's eclipse is finished. Professor Dr. Miloslav Druckmuller, a world expert in processing images like these have created some mathematical methods to cope with the huge dynamic range in brightness of the Solar Corona. I collaborate with him since many years now and these results are always beyond our imagination!

For me since I'm an amateur astronomer and do it in a volunteer basis, beeing able to capture data that create images like these is like a dream coming true every time! It takes so much effort and multihour travelling to make an Eclipse expedition, but its so rewarding to get a glimpse of the internal solar corona with high detail! Look how many stars can be seen near the solar limb!

How to Report a Comet Discovery

How to Report a Comet Discovery
by David H. Levy
So you think you’ve found a comet?
Here are some steps to follow in verifying your find:
Examine the object carefully. Is it symmetrical? If it is, chances are it’s a galaxy. Does it have a mottled, circular appearance? Maybe it’s a globular cluster. Switch to higher magnifications to try and see if you can resolve the individual stars.
Does the "comet" shift in position when you move the telescope around? It could be just a "ghost image" (internal reflection) in your telescope optics. Even if the object shows an obvious tail, make sure it isn’t something like Hubble’s variable nebula.
According to the International Astronomical Union’s Central Bureau for Astronomical Telegrams (CBAT), the world’s clearinghouse for astronomical discoveries, more than 90 percent of all first-time comet reports turn out to be spurious.
Check its position (in right ascension and declination) on a suitable star atlas or sky-charting program. Make sure there are no known galaxies, star clusters, or nebulae plotted in that location. (If you’re using a sky program, don’t forget to have its limiting magnitude set faint enough.)
Note the object’s position relative to the background stars. If the suspect doesn’t show any movement within an hour, it’s probably not a comet.
Get a friend or a trusted member of your local astronomy club privately to confirm your find visually, photographically, or with a CCD camera. Multiple observations within a single night or on a second night are highly recommended.
Check Web sites, for lists of newly discovered comets or returning periodic ones to see whether you have picked up a known comet.
If you’re certain you have indeed discovered a new comet send an e-mail to CBAT at cbat@cfa.harvard.edu, or go to its Web site. CBAT needs to know the following:
the exact date and time of your observation in Universal Time
your observing site and telescope used
the object’s precise coordinates (in equinox 2000.0)
its rate and direction of motion
its estimated magnitude
its physical descriptionDon’t forget to include your name, postal address, phone/fax, and e-mail.

Good luck, and happy hunting!

The Edgar Wilson Award

The Edgar Wilson Award August 23, 2009by J. Kelly Beatty Each night giant telescopes around the world scan the sky for new solar-system objects, so it would be easy to conclude that the era of comet discoveries by amateur astronomers is over. But that's not the case! It's still possible for amateurs to bag interplanetary visitors that professional automated sky surveys miss. In fact, backyard observers continue to play a valuable role in finding and tracking new comets. Sky & Telescope contributing editor David Levy shared in the 2007 Edgar Wilson Award for his discovery of a periodic comet the previous year. IAU Central Bureau for Astronomical TelegramsNow amateur comet discoverers receive more than just naming rights and hearty congratulations for their efforts — because they can qualify for the Edgar Wilson Award. Established in 1998 in memory of American businessman Edgar Wilson, the award is given to amateurs (or to professional astronomers acting in an amateur capacity) who, in a given year, find one or more new comets using amateur, privately owned equipment. Wilson, who lived in Lexington, Kentucky, had a keen interest in astronomy before his death in 1976. Under the terms of his estate's bequest, the Smithsonian Astrophysical Observatory administers the award through the IAU's Central Bureau for Astronomical Telegrams. Awardees receive individual plaques and share a cash prize. Recently the latter has totaled about $20,000, which is usually divided among two to six amateur individuals or groups. Not since the 1880s have backyard observers stood to gain such sizable financial bounty for their finds. The comet discoveries can be visual, photographic, or electronic; those made using spacecraft data, such as from SOHO, don't qualify. In years when no such discoveries are made, the SAO will present the award to amateurs who have made major contributions to promoting cometary studies.

11/08/1999 Total eclipse. I was down there in umbra on time

Here is what the Earth looks like during a solar eclipse. The shadow of the Moon can be seen darkening part of Earth. This shadow moved across the Earth at nearly 2000 kilometers per hour. Only observers near the center of the dark circle see a total solar eclipse - others see a partial eclipse where only part of the Sun appears blocked by the Moon. This spectacular picture of the 1999 August 11 solar eclipse was one of the last ever taken from the Mir space station, which was deorbited in a controlled re-entry in 2001.
