Solar Eclipse Calendar for 12 February
February 12, 1431 "In (the month of) Jumada al-Ukhra, the astrologers warned that the Sun would be eclipsed, and in Cairo there were callings to the people that they should pray and do good deeds. However, the eclipse did not occur and those who gave the warnings were denounced. Then news arrived from al-Andalus (Islamic Spain) of the occurrence of an eclipse there covering all of the Sun's body except one-eight of it. That was after midday on the 28th of the month." From: Al-Maqrizi, al-Saluk fi Ma'rifat Duwal al-Muluk. " In (the month of) Jumada al-Ula it was known that the calendar experts agreed that the Sun was to be eclipsed on the 28th of the month after the Zawal (i.e. after the Sun had crossed the meridian). The Sultan and the people were prepared for it and were watching the Sun until it set but nothing of it had changed at all." From: Al-'Asqalani, INBA' AL-Ghumr bi 'Bna' al-'Umr. These two quotations refer to total solar eclipse, expected in Cairo, but visible in Spain, of 12 February 1431.
February 12, 1431 "On February 12 at about the 21st or 22nd hour, the Sun was completely obscured and in front of the Sun was placed a black circle like a little wheel. It became as dark as night and the sky revealed the stars. The birds went to roost as they usually do at night. Everyone was feeling ill at ease as a result of this event. It began half an hour before the Sun was covered over. It gradually lost its light even to the hour stated above. . ." Refers to a total solar eclipse in Perugia, Italy, of 12 February 1431. From: Antonio dei Veghi, Diario dall'anno 1423 al 1491.

February 12, 2002 HESSI is operational. It detected its first flare, a C2 flare early on Tuesday morning, February 12, starting at 0214 UT. The spacecraft is balanced and spinning at 14 rpm about an axis within about 0.1 degrees of the Solar Aspect System (SAS) axis. We should get accurate aspect in-formation once the data from the SAS and the Roll Angle System are fully analyzed.
