28 Days Later

Time, as they say, waits for nobody and when I look back towards the beginning of the month I am left wondering where all the time has gone. March began (01.03.09 & 02.03.09) by bidding a fond farewell to comet Lulin as it started the long journey back out towards the distant reaches of the solar system. Around this time I also logged the open cluster M47 from the Binocular Messier Club list with the 10×50s, but with an elevation of around +18° M47 offered a rather sketchy observation as it drifted through the southern sky glow.  I had also tried to catch two other open clusters in this part of the sky: M46 (which is very close to M47) and M50 in Monoceros. Both remained hidden from view, again due to the sky conditions, but I am going to make every effort to catch these two objects before they disappear into the summer evenings.

Besides my Lulin and Messier observations, the beginning of the month (05.03.09 & 06.03.09) also offered me the perfect opportunity to study the cratered surface of the waning gibbous Moon and score a number of objects from the Lunar 100 list. The most notable objects included the Vallis Alpes, the crater remnant Hipparchus as well as the mysterious Bessel Ray and the ancient crater of Clavius. Aside from viewing a good many Lunar 100 objects I also took the time to explore many features beyond the scope of the list and I made wonderful observations of prominent impact craters such as Reinhold, Herschel, Eudoxus, Aristoteles and many more.

Beyond this point bad weather conditions brought things to an abrupt end for almost two weeks, so it was nearer to the end of March (21.03.09) before I managed out, this time turning my gaze towards two faint galaxies in Canes Venatici: Messier 94 and Messier 63. However, the immediate interference of a neighbor’s extremely intrusive light combined with the neck breaking altitude of +41° put paid to a more in-depth observation. I dare say that I will return to these two deep sky objects in the next few months when they are both in a better position.

Following on from this I then  spent some time a few mornings later (24.03.09) hunting down three more Messier objects: the open clusters M29 and M39 in Cygnus as well as the planetary nebula M27 in Vulpecula. I couldn’t have asked for better conditions and I easily tracked down the two open clusters but the urban terrain combined with a low position in the sky unfortunately prevented me from viewing M27. In addition to my deep sky observations I  serendipitously caught two satellites through the 25×100s as they shot over the eastern sky. After some digging around on the web I whittled my options down to two possible designations: A0-27 and ITAMSAT 1. I’ve never been very good at catching iridium flares or tracking satellites, so I still have some niggling doubts over the identities of the two space craft, but it seems as though A0-27 and ITAMSAT 1 are my best bet.

To finally wrap things up I took in a short view of Saturn and the cloud enshrouded Titan as they sat serenely under the watchful eye of Leo. Upon making this observation I originally thought that I’d also seen the small Saturnian moon of Iapetus, but later investigation revealed that it was in fact HP 54954, a 9th magnitude G class star about 365 light years distant. So unfortunately, no cigar.

In retrospect March has definitely been a celestial smorgasbord, but as MoonWatch week is upon us UK amateur astronomers I plan to spend much of my time gazing at the checkered lunar surface. Hopefully the elements will cooperate and grant me some decent Moon watching weather.

The Washed Out Sky

Located between the constellations of Leo and Bootes lies the ambiguous Coma Berenices. Made up of three stars that all shine at magnitude 4: α Com, β Com and γ Com, it is a faint constellation and especially so under skies saturated with light pollution.  However, while Coma Berenices may seem to be an uncomplicated and uninteresting constellation it is in fact a treasure trove of deep sky objects just waiting to be found.

It was here early on Friday morning (06.02.09) that I concentrated my hunt for two Messier objects: the globular cluster M53 and The Black Eye Galaxy M64. With the waxing gibbous Moon hanging over the north western horizon, conditions were less than cooperative. That’s not to say that the actual sky conditions were bad, on the contrary the seeing was excellent and transparency was the best I’ve seen for a few weeks, but with the setting Moon casting it’s achromatic light, deep sky observing was made all the harder.

Finding Coma Berenices was the hardest part of this observing session, but once I did it was all pretty straightforward from there on in. Aiming the 25×100s on α Com I was surprised to find that M53 (just sitting north west of the star) was clearly visible as a dense, vivid smudge against the washed out sky. I spent around fifteen minutes studying this condensed globular which was (in my opinion) far superior to the view that M92 offered a few mornings earlier. Averted vision yielded little more detail than I could already make out, perhaps because of the Moon light or perhaps because they’re was no more detail to be had. Either way, I’m looking forward to returning to this globular in darker conditions to carry out an extended observation of it.

The Black Eye Galaxy or M64 as it is better known was the next object on the agenda, but considering the conditions I was less than optimistic about grabbing a successful observation. I made a try for it regardless, but as I predicted this was one galaxy that was just out of reach, at least for the moment. Leaving M64 behind for another time I took the opportunity to take in another view of M13 in Hercules - even under a Moon lit sky this mighty globular cluster still delivers a truly fabulous sight. It really is quite something else to realise that you are gazing upon several thousand (possibly millions) of stars lying over 25,100 light years away. If that doesn’t make you dizzy with awe, I don’t know what will! With the time hitting 03:15 UT I decided to call time on my session - just as well really, as a vast bank of cirrocumulus slowly began to consume the sky as it drifted south eastwards. I’ll return to M53 and M64 later in the month (weather allowing) when the Moon rises later; I’ll also be on the lookout for the open cluster M39 in Cygnus so watch this space!
