Comet 220P/McNaught on June 8, about a week after its major outburst. Despite fading to around mag. 11, it still showed a broad green coma, a bright central condensation and a dust tail with a distinct central spine. #astronomy #comet ℹ️ cometografia.es/220p-mcnaugh...

C/2025 R3 (PANSTARRS) on May 19. This wider-field image revealed far more of the comet than my close-up view: a vivid bluish-green coma, a short dust tail, and a remarkably sinuous ion tail stretching about 6.5° through rich galactic nebulosity. #astronomy #comet ℹ️ cometografia.es/2025r3-panst...

Comet 88P/Howell remains near mag. 11 despite receding from the Sun. Its bright emerald-green coma is still prominent, while the tail has grown markedly over the past month, now reaching about 0.5°. The orange star pair makes a striking contrast. #astronomy #comet ℹ️ cometografia.es/88p-howell-2...

Last days to observe comet C/2025 R3 (PANSTARRS) from the Northern Hemisphere, as it drops rapidly into the dawn sky on its way toward the Sun. Although the Moon will be gone, the comet will sink deeper into twilight with each passing day.

Comet C/2025 R3 (PANSTARRS) one week ago at mag. 6 Ion tail extending well over 1°, showing streamers and a narrow, slightly twisting main feature. Imaged at just 15° altitude under a Full Moon—conditions that make this result especially rewarding. ℹ️ cometografia.es/2025r3-panst... #astronomy #comet

Comet C/2025 R3 (PANSTARRS), Mar 23, was clearly improving: already at mag. 7.6, with an ion tail reaching ~1° and starting to reveal structure. Only 15° above the horizon and under poorer sky conditions… definitely an interesting target ☄️✨ ℹ️ cometografia.es/2025r3-panst... #astronomy #comet

Comet C/2025 R3 (PANSTARRS) brightened to mag. 8 a month ago, after solar conjunction —evolving from a telescopic patch into a binocular object, vivid green coma and faint ion tail ~0.5°, despite low altitude and twilight.
