OT - the Lunar Eclipse of 28 September 2015 from Leiden

Leiden had clear skies during the night of September 27-28, which meant a good view of the total Lunar Eclipse in the early morning of September 28.

For me, this eclipse occurred mostly at rooftop level, with the moon sinking from 34 degrees elevation at first contact with the umbra, to 11 degrees elevation at last contact with the umbra. During mid-totality, at 2:47 UT (4:47 am local time), the moon was at 21 degrees elevation, just disappearing behind the rooftops for me.

After setting up my Celestron C6, I could use the telescope until about 2:40 UT, when the moon disappeared behind the rooftops. I then went to my girlfriend's appartment, which (from the 2nd floor) has a good view Westwards, and continued photography with simpler means during the second half of the eclipse.

There I shot a series of images with the Canon EOS 60D and the EF 2.5/50 mm Macro lens on a tripod. 14 of these images, shot in 5-minute intervals, where then stacked to create the image above, which shows the second half of the eclipse from 03:15 UT to 04:20 UT, i.e. from late totality until just before last contact with the umbra. The lens was set at F5, camera on 250 ISO, and exposure times were 4 seconds at the start of the series, and 0.5 seconds at the end. It shows that you don't need a telescope to get nice pictures.

Of course, a telescope does allow for very fine pictures. Below are some results from the first half of the eclipse, taken with my Canon EOS 60D through my Celestron C6 (15 cm F/10 Schmidt-Cassegrain with F6.3 focal reducer):

This was a rather dark eclipse, to my estimate at the edge of L1/L2 on the Danjon Scale. The best moment for me was just before totality, when the moon sat just above the roof as a dark red-purple globe with a bright crescent on the lower edge: it looked a bit like Mars with a polar cap this way.

And by the way: NO! I refuse to go along with that "Super Blood Moon" nonsense. Puh-Lease!!!!

The "Blood Moon" denomer is actually of very questionable origin. It is not (contrary to what some people seem to think) an old folkloristic name for a Lunar eclipse, but is a denomer coined only a few years ago by two American Christian religious doomsday fanatics, who prophecied that the tetrad (series of four lunar eclipses each six months apart) starting with the eclipse of April 15, 2014 and ending with this eclipse of September 28, 2015, were a sign of the End of Times being near. They got their inspiration for this name from a sentence in the Bible, in the Book of Revelations.

Unfortunately, it seems everything in our modern society has to be expressed in ridiculous hyperbole nowadays. Ad to that media ignorant of the origin of the denomer "Blood Moon" with some religious crackpots, and you end up with horrible abominations like "Super Blood Moon" for what in essence was a nice and impressive, but in itself not particularly distinctive or rare Lunar eclipse...

Yesterdays longer USA 193 related TV interview now on-line (expanded 11:00 GMT)

(expanded 22 Feb, 11:00 GMT)

The last two days were pretty hectic and tiring here. After my short appearance in Wednesday evening's 10 pm TV news, I had another TV-crew visiting me yesterday afternoon, for a longer item in NOVA, a well-watched program on Dutch national television providing in depth backgrounds to some news topics of the day.

It was a good interview, and a much longer item than Wednesday's short tv-news item, with several minutes of me being interviewed at my home. The questions asked were good, focussing on the "why?" of this whole thing and the extend as to what "we" (as active satellite observers) know about these classified satellites. The broadcast can be seen here:

There was a studio guest too: the resident space related Dutch TV expert Piet Smolders. Amongst others he raised the possibility of nuclear fuel being on board (something I had avoided), and mistakenly says this is the first time the US shoots down a satellite (they did it earlier in September 1985, targetting the Solwind satellite).

In the above screenshot (with thanks to Jacob Kuiper), note the book "comets" which was placed there on request of the camera-man for visual appeal. Also, the NASA "Certificate of Appreciation" (related to my participation in the 1998 Leonid multi-instrument airborne science mission) normally hangs on another part of my wall, but was placed there on a similar request... :-)

Earlier that day, at about 7:15 am in the morning, I was called out of my sleep by the Dutch NOS radio news for a comment to the news of the successful ASAT attack in the 8 am radio news. I was still quite groggy, as I had been up at 4 am to watch the lunar eclipse!

A local radio station called too that afternoon, but by that time I was so tired (and had an agreement with the people from NOVA not to comment elsewhere before the broadcast) that I declined.

All the media attention to the USA 193 story caused another prominent peak in my webstats for this site again the past days:



Among the more interesting visitors was for example this one:



Oh: and the total Lunar Eclipse? For a short while around the start of totality (4 am local time), the moon managed to show up through hazy cloud cover. I managed to shoot a few pictures under apalling conditions, the best of which is these:



But I have been lucky to have seen and photographed anything at all, most Dutch and Belgian observers missed it completely due to the weather.
