The newly discovered very-NEO, 2024 RW1 collided with earth over the Philippines several hours after discovery. The collision occurred on 2024 Sep 4 12:46 EDT (1646 UT). The estimated diameter was ~1m. This was the ninth MP to be discovered before impact.

Here's an article about the resulting fireball:

CNEOS predicts that the newly discovered NEO, 2024 RJ2, made a close approach on 2024-Sep-05 04:34±<00:01 UT at a distance of 0.02712 AU moving with V Relative=15.95 km/sec, H=23.3 magnitude, diameter 57 m - 130 m and 'Rarity'=1. There is a 2 day observation arc, the Condition Code=8 and the Earth MOID=0.0271043 AU. The solution date was 2024-Sep-05 06:26:01 PDT. The initial reported observation was by ATLAS Chile, Rio Hurtado on 2024-09-03.

Using MPC's elements for 2024 Sep 5 0000 UT, ST4.1.11.10 Visual Pro predicts that this NEO will reach a peak brightness of 15.9 magnitude on 2024 Sep 6 at 0200 EDT traveling through Aquarius at 43.5"/minute. The close approach was predicted (to the nearest hour) on 2024 Sep 5 at 0100 EDT when the NEO was traveling through Aquarius at 49"/minute at 16.4 magnitude.

CNEOS predicts that the kilometer-sized, Aten class NEO, (66146) 1998 TU3 will make a close approach on 2024-Nov-05 19:47±<00:01 UT at a distance of 0.08884 AU moving with V Relative =11.53 km/sec, H=14.4 magnitude, diameter 2.864±1.165 km and 'Rarity'=3. As of 2024 Aug 25, there is a 15239 day observation arc, the Condition Code=0 and the Earth MOID=0.0734514 AU. The solution date was 2024-Aug-25 05:48:53 PDT. This NEO was discovered at Socorro on 1998-10-13 by LINEAR. Its not on MPC's list of PHAs due to the large Earth MOID. This is another 'Rarity'=3 event and SkyTools predicts that this MP is already ~15.3 magnitude in Taurus at 0.48 AU distance.

Using MPC's elements for 2024 Aug 28 0000 UT, ST4.1.11.10 Visual predicts that this NEO will reach a peak brightness of 11.6 from the morning of 2024 Oct 27 in Eridanus at 0.11 AU distant to the evening of 2024 Nov 1 in Horologium at 0.09 AU distance. The close approach is predicted to occur (to the nearest hour) on 2024 Nov 5 1500 EST when the NEO will have faded to 12 magnitude traveling through Hydrus at 10.7"/minute in daylight and below the horizon in Columbus, Ohio.  It will move too far south to be visible from Columbus, Ohio  on the morning of 2024 Oct 29, unfortunately. This close approach will be best for southern hemisphere observers, weather permitting.

This object will be visible in medium sized scopes for quite a while from both hemispheres, so there should be many opportunities to observe it.

Good Hunting,

CNEOS predicts that the kilometer-sized NEO, (276049) CE26, will make a close approach on 2024-Sep-11 14:07±<00:01 UT at a distance of 0.17928 AU moving with V Relative=25.89 km/sec, H=16.7 magnitude, diameter 3.5±0.4 km and 'Rarity'=1. There is a 8278 day observation arc, the Condition Code=0 and the Earth MOID=0.0966314 AU. The solution date was 2024-Aug-25 05:48:53 PDT. This NEO was discovered at Socorro on 2002-02-10 by LINEAR. This object is approaching 16th magnitude and will have a broad light curve due to its large size and distance. It won't be a fast mover; however, due to the distance. This MP's MOID isn't close enough to make MPC's list of PHAs, but it's a big one.

Using MPC's elements for 2024 Aug 25 0000 UT, ST4.1.11.10 Visual predicts that this NEO will reach a peak brightness of 14.9 magnitude on the evenings of Sep 7-9 at a distance of 0.18 AU traveling through Aquila at ~11"/minute. Close approach is predicted to occur (to the nearest hour) on 2024 Sep 11 1000 EDT when the NEO is at a distance of 0.18 AU traveling through Sagittarius at 12"/minute in daylight, but below the horizon as seen from Columbus, Ohio.

Bonjour, est-il possible de récupérer un horizon obstrué créé avec skytools imaging pour l'exporter vers un xls ou le sauvegarder ?

Here's an article about a commercial attempt to mine a metal-rich asteoid that looks interesting:

Against all odds, an asteroid mining company appears to be making headway | Ars Technica

For obvious reasons, they don't identify the asteroid of interest. They don't want any claim jumpers. Pretty cool.

There's new research about the asteroid that killed the dinosaurs (and 70% of the other life on earth) 66 million years ago. The 10 km diameter object seems to have come from the outer solar system beyond Jupiter, unlike the more recent impacting objects. Researchers analyzed the isotopes of ruthenium in the K-T boundary layer at the end of the Cretaceous period to make their determination. Here's a link to the article:

Good afternoon,
Is there a complete NGC catalogue available via Skyhound ? If there is one, where and how can i download it ?
Wouldn't it be usefull to have complete NGC-catalogue, so that you can see in 1 catalogue wich Ngc you already have observed.

thank you

I've tried multiple ways to clear out the Letter P ( blue box ) on the Far Left Column of the Target Selection Tab. I am aware this indicates an active Project.

Although......the projects ( Eastern & Western Veil ) do not appear in the Scheduler Tab.
The projects are marked complete in the Observations Tab - so it makes sense for the projects not to show up in the Scheduler Tab. 

But why are these completed projects still showing up in the Target Selection Tab ? The Observations Tab indicates the projects are complete.

I have included screens shots for reference - hoping I would find the answer easily in this forum and something simple I am overlooking.

thank you in advance
