Solar eclipse and the aurora borealis

In the North Russia area where totality will begin at sunrise, the aurora borealis could also be visible up to the beginning of the nautical twilight, depending on the intensity of the auroral activity at that date. If an extremely high intensity geomagnetic storm takes place simultaneously, there might be chances of seeing the aurora simultaneously with the eclipsed sun. In the east of Taymyr Peninsula the total phase will start at August 13 at 0:00 local time during midnight sun.^[1]

Solar eclipse below the horizon

Due to the considerable eclipse magnitude (more than 0,8), observers where the totally eclipsed sun is just below the horizon will have the chance to observe the lunar shadow in the high atmosphere, as well as shortened civil twilight and extended nautical twilight. The darkening of the twilight sky could improve the chances of observing the inner Zodiacal light.^[2]

Eclipses in 2026

• An annular solar eclipse on February 17.
• A total lunar eclipse on March 3.

Solar eclipses 2026–2029

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.^[3]

Saros 126

It is a part of Saros cycle 126, repeating every 18 years, 11 days, containing 72 events. The series started with partial solar eclipse on March 10, 1179. It contains annular eclipses from June 4, 1323 through April 4, 1810, hybrid eclipses from April 14, 1828 through May 6, 1864 and total eclipses from May 17, 1882 through August 23, 2044. The series ends at member 72 as a partial eclipse on May 3, 2459. The longest duration of central eclipse (annular or total) was 6 minutes, 30 seconds of annularity on June 26, 1359. The longest duration of totality was 2 minutes, 36 seconds on July 10, 1972. All eclipses in this series occurs at the Moon’s descending node.

Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's descending node.
