The average sunspot number for May 2024 was 172, the highest value in 22 years. So far, June is even higher at 200. If this continues for the rest of the month, June could log the highest sunspot counts since Dec. 2001, rivaling the peak of potent Solar Cycle 23. Solar flare alerts: SMS Text
THE LASER-LIKE ANTI-TAIL OF COMET 12P: Today, Earth is passing through the orbital plane of comet 12P/Pons-Brooks. “This is causing it to develop a laser-like anti-tail,” reports astronomer Ian Griffin, who sends this photo from Otago, New Zealand:
“It was an amazing display,” says Griffin.
In Griffin’s photo, the anti-tail is the very sharp line pointing toward the upper right. It’s “anti” because it points directly opposite the comet’s regular gas tail (lower left).
What is this anti-tail? It’s an optical illusion. Anti-tails appear when Earth passes through a comet’s orbital plane. During the crossing, the sharp edge of the comet’s fan-shaped dust tail narrows to a laser-like line and appears to point toward the sun.
This phenomenon will be visible for the next few days. Southern hemisphere astronomers can find the comet in the constellation Lepus ~20 degrees below the celestial equator. With a magnitude of +7, the comet is an easy target for amateur telescopes. Submit your photos here.
