Tiga fenomena luar biasa di langit : Gerhana Bulan dan Matahari pada Jun dan Julai ini.


Sebelum waktu tengah malam 1 Jun 2011 di Tromso, Norway, gerhana Matahari separa akan kelihatan seolah-olah tergantung di bahagian ufuk utara.

Bulan hadapan, dunia akan mengalami tiga kejadian gerhana iaitu dua gerhana Matahari separa pada dua bulan yang berlainan dan satu gerhana Bulan penuh yang berlaku betul-betul diantaranya, dan semuanya bermula dengan gerhana Matahari yang dipanggil gerhana Matahari "tengah malam".

Gerhana Matahari ini akan terjadi pada 1 dan 2 Jun 2011 yang dapat dilihat di kawasan paling utara iaitu di Amerika Utara, Eropah dan Asia.

Peta kenampakan kedua-dua gerhana Matahari ini dapat dilihat dengan melayari laman web ini http://eclipse.gsfc.nasa.gov/OH/OH2011.html.

Gerhana Matahari "Tengah Malam" 2 Jun 2011

Gerhana Matahari ini akan bermula pada hari Khamis 2 Jun 2011 iaitu pada waktu subuh di Utara China dan Siberia , kemudiannya bergerak menyeberangi Artik, menyeberangiGarisan Tarikh Antarabangsa dan berakhir pada awal petang Rabu, 1 Jun 2011 di Timur Laut Kanada.

Adalah benar gerhana ini bermula pada pada hari Khamis dan berakhir pada hari Rabu disebabkan oleh Garisan Tarikh Antarabangsa. Ini kerana pemerhati - pemerhati di bahagian Utara Rusia dan Scandinavia akan dapat melihatnya berada di atas Kutub Utara dimana mereka akan dapat melihatnya betul - betul pada waktu tengah malam antara 1 Jun dan 2 Jun.

Gerhana Matahari yang tidak dapat dilihat pada 1 Julai 2011

Gerhana Matahari separa yang tidak dapat dilihat sesiapa pada 1 Julai 2011. Hanya kelihatan di lautan Selatan kawasan pantai Antartika.

Tepat sebulan kemudian iaitu pada 1 Julai 2011, satu gerhana Matahari yang aneh akan terjadi di Antartika. Disebabkan musim sejuk di kawasan selatan, Matahari akan berada di bawah ufuk untuk semua kawasan Antartika kecuali di satu kawasan kecil yang tidak berpenghuni di pantai selatan Madagascar. Satu-satunya kawasan di mana gerhana dapat dilihat di ufuk ialah di satu kawasan kecil pantai Selatan, jauh ke selatan dari Afrika Selatan. Pemerhati yang mungkin berpeluang untuk menyaksikan gerhana ini berlaku ialah peguin dan burung-burung laut.

Gerhana Bulan Penuh 16 Jun 2011

Betul - betul diantara dua gerhana Matahari Separa ini akan terjadinya satu gerhana Bulan Penuh pada 16 Jun 2011. Gerhana ini akan dapat dilihat oleh berjuta-juta pemerhati di Afrika, Timut Tengah dan Barat Daya Asia. Ianya akan kelihatan ketika Bulan terbit pada awal petang di Selatan Amerika dan Eropah dan ketika Bulan terbenam sebelum subuh di kawasan Asia dan Australia Timur. Walaubagaimanapun ianya tidak akan kelihatan di mana-mana kawasan di Amerika Utara.

The new moon will come tomorrow, on Wednesday, June 1, 2011 at 21:03 Universal Time. That’s 4:03 p.m. Central Daylight Time here in the United States. As seen from most of the world, the new moon will swing north of the solar disk. That means many of us won’t be able to see the partial eclipse of the sun tomorrow.

However, if you live in northeast Asia, or at Arctic and sub-Arctic latitudes, you might be able to witness the new moon moving in front of the sun and taking a bite out of the sun’s disk. In addition to northeast Asia, the partial eclipse of the sun will be visible from northern Siberia, northern Alaska, northern and eastern Canada, Greenland, Iceland, and northern Scandinavia.

The partial solar eclipse will happen either tomorrow or Thursday, depending on your time zone. If you’re in a position to watch this partial solar eclipse, be sure to use proper eye protection.

Eye safety during solar eclipses

Places that will see the partial solar eclipse on June 1 include Alaska, Canada, Greenland, and Iceland. Late in the day on June 1, northernmost Finland, Sweden, Norway, and the Arctic coast of western Siberia will see the eclipsed midnight sun skimming along their northern horizon.

Places that will see the eclipse starting at sunrise on Thursday, June 2, 2011 include North Korea, northern Japan, eastern Mongolia, and northeastern China. Elsewhere in northeast Asia, the eclipse will be visible sometime during the morning hours on June 2.

Meanwhile, if you live in northern Alaska, northern and eastern Canada, Greenland, Iceland, and northern Scandinavia, look for the partial solar eclipse during the daylight hours on June 1. Wherever you may be, remember that it’s of the utmost importance to use proper eye protection!
