AI Thread Summary
An Aurora Watch alert was issued on August 21, 2013, following a coronal mass ejection (CME) from a solar filament eruption observed on August 20. The CME is expected to reach Earth around August 23, with a potential for auroras, although it will be a glancing blow directed mostly south. Recent similar CMEs have shown a greater capacity to produce auroras than anticipated, due to unique magnetic field structures. Aurora enthusiasts are encouraged to monitor updates on the event through the IPS Radio and Space Services website. The discussion highlights excitement and interest in aurora photography among participants.

hey guys
anyone interested in seeing and or photographing aurorae
an alert has been issued today 21 Aug 2013

SUBJ: IPS AURORA WATCH
ISSUED AT 0043 UT ON 21 Aug 2013 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE


A coronal mass ejection from a solar filament eruption was observed on
the 20th of August and is expected to strike the Earth midway through
the day on the 23rd of August UT (around midnight or early morning on
the 24th of August AEST). The CME was directed mostly to the south, so
this will be a glancing blow at best. However, recent CMEs of solar
filament origin have been more effective at producing Auroras than
might be expected from coronagraph images alone, due to the magnetic
field structures within the ejected plasma behaving differently to
flare produced CMEs and being more favourable for producing Aurora.

Significant uncertainties in the analysis of this event remain, so
Aurora watchers are advised to follow the progress of this event at
http://www.ips.gov.au/.


AEST = Australian Eastern Standard Time

Fascinating. Thanks for the heads up dave.
 
Nice! I wish I was back in Iceland! :(
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
