Are the weather maps on @BOM_au's new website a bit funky for anyone else?

[Brett Carter @DrBrettCarter]

This seems familiar @Vincent_Ledvina... 🤔

Unfortunately, I am seeing a lot of these posts, which means there are still a lot of folks out there who do not know the main #aurora show from this ongoing #solarstorm already happened last night-- the storm arrived earlier than expected. As for tonight's chances, they are much lower, and unless you see dedicated chasers from our online #SpaceWeather community reporting in, it is likely that there just aren't bright enough views to be had tonight.

Aurora in Melbourne, Australia right now!

[Brett Carter @DrBrettCarter]

Still visible now, but very dim to the naked eye...

[Brett Carter @DrBrettCarter]

Aaaaaaaand it's gone...

Goes to show how agile the aurora can be! Literally packing the car up to go to a south- looking beach, and there it was over head!

20 seconds later, it died down significantly...

@Vincent_Ledvina Welcome mate!

The G4 #solarstorm level is legit. In fact, looking at the Hp30 index, which is just like Kp but it averages 30-minute instead of 3-hour intervals, you'll see we entered G5-level territory at 17:30 UTC. This was exactly when The New Zealand National Grid issued a proactive alert!

🚨 Slingshot Orbital Alert 🚨

Slingshot is actively tracking the fragmentation of DMSP-5D2 F14 (Norad: 24753). The event was first publicly reported by https://t.co/ELi6kQuwKF as occurring at 02:10 UTC, although detections from Slingshot’s LEO optical fences indicate the fragmentation likely occurred on December 19th, 2024 prior to 01:15 UTC.

According to Slingshot Seradata, this 27 year old, 750kg, retired satellite is owned by the National Oceanic and Atmospheric Administration (NOAA) and was part of the Defense Meteorological Satellite Program. The database further indicates a relatively high failure rate of 44% for satellites from this bus family. The satellite is on a sun-synchronous orbit, at an altitude of approximately 850 km.

The event was first detected by one of our Horus LEO optical fences in Chile. Another Horus system, located in South Africa, later generated additional collects, and our orbital analysts confirmed the event shortly thereafter.

We are currently tasking the Slingshot Global Sensor Network to collect additional photometric and astrometric data on the parent object and neighboring fragments. We will provide more updates as they become available.

The video below shows the parent object (DMSP-5D2 F14) entering the frame in the lower right corner of the video at the 5 second mark. A train of objects correlated as associated debris follow the parent, each highlighted in yellow.

We’ve temporarily made the DMSP-5D2 F14 Seradata page publicly available where you can find contextual data on the spacecraft: https://t.co/aensBDdFBH

Seradata is the industry-leading launch and satellite database, with information including:

🛰️ – Spacecraft Data: Owner, operator, mission, sector, orbit, age, status, payloads, capacity, subsystem data, etc.

🚀 – Launch Data: All orbital launch attempts (successes and failures), relevant sub-orbital launches, launch vehicle specifications, launch vehicle history, launch orders, future launches, etc.

📊 – Anomaly & Insurance Data: Reliability and failure trends for launch vehicles and spacecraft buses, historical insurance claims and loss values, company reports (including financials), etc.

Government is to cancel the ADF's JP9102 Advanced Satellite Communications project.

This is a big step backwards for Australia's future in space, and follow's government's decision to cancel the National Space Mission for Earth Observation (NSMEO) last year for 'budget repair'.

Australia's space sector is not getting the support it needs from the current government, and progress towards a future sovereign space capability has been thrown into reverse.

Green and red #aurora holding their own against the streetlights of Lancaster! #northernlights @bbcweather @BBCNWT @liamdutton

Just sent an email to over 22,000 people summarizing aurora chances and viewability for tomorrow!
Time to charge those batteries!

[Vincent Ledvina @Vincent_Ledvina]

This is NOT a Carrington event.
This is NOT a "killshot." There is a 0% of that.
This does NOT look like May 10 events (imho).
There is no way to predict exact auroral visibility at this point, but mid-latitude auroras are possible. We need to see what the CME looks like at L1.

@Vincent_Ledvina Be sure to hit up a Yamachan mate... chicken wings n beer...

An excellent thread...

[Vincent Ledvina @Vincent_Ledvina]

HOW TO CHASE THE G3 GEOMAGNETIC STORM AURORA TOMORROW - MEGATHREAD!

Let's assume the CME just hit and you are ready to go out? What should you do? What data do you look at? Where should you drive? How do you take a photo?

As a professional aurora chaser, let me explain...

[Andrew @asphotos]

Going off at Mt Buller - cloudy in melbourne. Seeing reports as far north as Canberra.

A bit of colour behind the clouds 🙂 #aurora #auroraaustralis #tasmania
