Sebuah lagi komet menghampiri matahari dan sedang berada terang dilangit timur pada awal pagi (mengikut laporan pemerhati sehingga magnitude 5.5!). Komet ini dijumpai oleh Southern Survey ASAS dan mempunyai core yang kecil dan padat berukuran angggaran 4 arcminit. Komet ini akan menghampiri matahari pada jarak terdekat pada 0.6 AU pada hujung bulan Februari ini dan dapat dicerap sehingga bulan Mac. Simulasi orbit komet C/2006 A1 Pojmanski  Cekupan dari Starry Night  Link ke laman web berkenaan dengan komet C/2006 A1 Pojmanski http://www.ast.cam.ac.uk/~jds/http://www.astrouw.edu.pl/~gp/asas/asas.htmlhttp://cfa-www.harvard.edu/iau/Ephemerides/Comets/2006A1.htmlTetapi malangnya kedudukan komet ini agak rendah (sekitar 20 darjah) dari ufuk timur, tetapi mana tau nasib kita agak baik dgn cuaca yg mengizinkan dapat juga mengintai komet ini. InsyaAllah. |

Baru sahaja lepas mencerap awal pagi tadi. Komet C/2006 A1 berada lebih kurang 2 darjah ke kiri bintang Dabih. Dari kawasan rumah saya di Alor Setar dengan mata kasar memang tak dapat nampak, tetapi mengunakan binokular, nampak titik kelabu koma komet tersebut. Mengikut pemerhatian pemerhati yang lain yg mengatakan komet ini ermagnitud 5.5, saya bandingkan dengan objek berdekatkan Sagittarius Cluster (M22) yang bermagnitud 6.5 serasa saya komet ini lebih kelam. Tetapi mungkin juga disebabkan oleh altitud komet ini yg rendah (gangguan atmosfera) dan juga langit sebelah timur saya yang agak tercemar dgn cahaya dari bandar Alor Setar.  Apa yang menarik semasa mencerap lebih kurang 2-3 buah satelit melintas langit timur. Esok insyaAllah try setup teleskop pula, tadi tak sempat pasal terlewat pula bangkit.  |

The weather around my area is horrible, the air is so moist that it keeps fogging up my viewfinder and wetting the maps. Besides that, its also very cloudy. Hopefully, I'll still get to see it. Here is a map for your reference. I'm going to use the starhopping method, since its already so hard to get started.  |

Hi Bentze,

Nampaknya saya la yang lucky fellow kat sini... Dah 3 hari berturut-turut berpeluang mengintai C/2006 Pojmanski ni. Tetapi jika dibandingkan dengan C/2004 Q2 Macholtz dulu rasa lebih baik kerana berada pada altitud yang lebih tinggi berbanding dengan Pojmanski yang rendah dan muncul hampir dengan terbit Matahari. Yang sama ialah warna kehijauan koma komet tersebut. Tapi rasanya my luck would just run out tonight... tadi dah nampak kepul-kepulan awan berarak dilangit Alor Setar.  |

I had some luck this morning. I starhopped to Dabih, as it did not seem very bright in the viewfinder. I started looking around.
After awhile, I found a slightly bright-roundish blob. I checked my map, and found that the area on the map that I had marked had no comet in it. I then realised I had marked the location of the comet for the 1th of March, and not the 28th(today). The mistake was only a few degrees off-course.
I found the experience very satsfying, as I had put alot effort into finding he comet. Problems like moisture in the air and clouds made it a bit harder to find the relatively bright comet.
However, I think I was a bit lucky to have found it beacuse I've heard that there have been many clouds in other areas
(that have probably been causing some serious banjir).
By the way, if you can't see the comet for any reason, you can always turn your scope towards Sagitarius. You'll keep yourself busy with nebulas, star clusters...

Nampaknya pagi ini pun nasib saya masih baik Kali ni sempat ambil gambar (bangkit awal sikit hari ni). C/2006 A1 Pojmanski sudah bergerak ke arah utara (dari kedudukan sebelah kanan bintang dabih sekarang sudah berada di kiri bintang dabih) dan kedudukan altitud juga semakin tinggi. Menggunakan kamera digital Canon Ixus-i, ISO 200, masa dedahan 10 saat. Proses imej "stack & align" dalam IRIS dan noise filtering dalam NEAT.  Bonus: Sempat juga tangkap Jupiter dan kedudukan Jovian moons nya. Gambar sedikit kabur tangan mengeletar oleh kerana terlebih kopi.  |
