medidas visuales de los cometas C/2023 A3 y 333P

#3389

Hola,

El pasado d铆a 2 sal铆 a intentar observar los cometas de primera hora de la noche a pesar del frente nuboso que se acercaba. El lugar escogido fue La Serra de Engarcer脿, interior de Castell贸n, un poco m谩s alto que el lugar habitual, a unos 800 m de altura, para evitar una peque帽a elevaci贸n que me pod铆a tapar el C/2023 A3. Calidad SQM al c茅nit de 21:03 y una T陋 de 7潞C

La visi贸n del primer cometa, el mencionado C/2023 A3, apenas se vi贸 afectada por el fino creciente de la Luna. El cometa se ve claramente m谩s d茅bil y menos concentrado que hace unas semanas. El siguiente objeto fue el 333P, con una coma muy difusa.

Por 煤ltimo intent茅 el C/2023 Q1 pero ya no lo pude observar pues las nubes me hab铆an tapado la zona del cometa.

Un saludo

Carles Labordena

Near-Earth asteroid 2024 PT5 in unusual orbit

This small Apollo asteroid (diameter ~11 m) was discovered on 7^th August 2024 by the ATLAS team from Sutherland, South Africa a day before passing Earth at 567,000 Km, or slightly less than 1.5 Lunar Distances (LD). It was 17^th magnitude and fading in the week following discovery and was below magnitude 21 by the end of that month.

Between 29 September 鈥� 25 November 2024 it passed just outside Earth's Hill sphere at a low relative velocity and became temporarily captured by the Earth鈥檚 gravity and received some press attention at the time as Earth鈥檚鈥榤ini-moon鈥�.

It is now approaching Earth again and will be closest on Jan 9 at 1.8 m Km (4.7 LD), reaching 18^th magnitude between 2025 Jan 6 鈥� 17.

The only subsequent close approaches in the next 100 years occur in 2055 (14 LD) and 2084 (4.4 LD).

The ephemeris below is appropriate for planning in the UK, but topocentric ephemerides can be generated for your location using the Minor Planet Center鈥檚 Ephemeris Service at:
