Recent Observations 8
The nights recently have been cloudy and cold. The moon on the night of 11/20/14 was in a waning crescent phase. I was able to find some circumpolar constellations, such as Ursa Minor and Cepheus. Also, using what I saw in Star Lab, i was able to find the great square of Pegasus.

Leonids Above Torre de la Guaita
During the morning of November 18, 1999, Europeans saw an increase in the number of meteors visible around 0210 UTC (counts growing up to 1000 per hour-- minimum amount for a "true meteor storm"). Observers, all over the world, saw between 30 and 100 meteors per hour. The picture is a 20-minute exposure and 5 Leonid meteors are seen clearly, as their tails blaze above the Torre de la Guaita (observation tower from 12th century--Girona, Spain). In 2014, over the span of the next few nights, the Leonids meteor shower will once again occur. However, this year the moon will be in a crescent (no skyglow) and Earth is thought to be passing through more debris left over from Comet Tempel-Tuttle than in 1999.

On Monday, November 10, 2014, I went outside around 6:30. In my observations, I managed to point out some constellations and observe the moon in the Waning Gibbous phase. Around 6:42, I was able to observe an Iridium flare directly above me.

Welcome to a Comet
The Rosetta Mission lander has successfully landed on the surface of C67/P Churyumov-Gerasimenko. Philae's technology can be seen in the bottom left side of the image and the device bounced twice on the surface before settling near a shadowing wall (blocking some illumination that was destined to power Philae through the solar panels). All in all, the landing has gone as planned and information is being sent back during communication windows.

Recently I was able to observe the full moon in the sky. I have been using the Internet in an attempt to find fall constellations in the sky and may have spotted a few. Of course I was able to find Cepheus and Ursa Minor (given that they are circumpolar).

Sh2-155: The Cave Nebula
The data in this photo were taken through narrowband filters (which track the glow of ionized sulfer, hydrogen and oxygen brand and displays this data in different hues). The cave is near Cepheus in appearance in the sky and it is 10 light years across (2400 away from Earth). The radiation is most likely causing the collapse of cores and well as new ones being created within.
