*Topic*: Total Solar Eclipse Impact on POES data *Date/Time(UTC) Message Issued:* 27 March 2006/1800 UTC *Satellite(s) Involved:* All NOAA POES *Instrument(s) Involved:* All Instruments *Product(s) Involved/Affected:* All products (except HRPT) *Date/Time(UTC) of Initial Implementation:* 29 March 2006, 0737 UTC (start of effect in POES data) *Details/Specifics of Change:* SOCC has reported the following:There will be a total solar eclipse on March 29th jday 088 from approximately 07:37 through 12:46Z. This sun-moon eclipse has been analyzed by the EMOSS eclipse model. This eclipse will affect all POES spacecraft over the course of 3 orbits.
On Wednesday, 2006 March 29, a total eclipse of the Sun will be visible from within a narrow corridor which traverses half the Earth. The path of the Moon's umbra1 shadow begins in Brazil and extends across the Atlantic, northern Africa, and central Asia where it ends at sunset in western Mongolia. A partial eclipse will be seen within the much broader path of the Moon's penumbral shadow, which includes the northern two thirds of Africa, Europe, and central Asia.
