AI Thread Summary
Heavy sunspot activity is anticipated during the solar poles' flip, potentially enhancing aurora visibility, but the current solar maximum is lower than in previous cycles. The number of sunspots may not significantly increase, and while more sunspots can lead to auroras, most displays are caused by Coronal Mass Ejections (CMEs), which are not always linked to sunspots. Historically, auroras have been visible at lower latitudes, particularly during equinox months like March and October. Coronal holes also contribute to geomagnetic storms that can produce auroras. Overall, while there may be opportunities to view the Northern Lights in November and December, the extent of visibility will depend on various solar activities.

There will be some heavy sunspot activity when the solar poles flip... should be some good aurora's...but how far south will they be viewable?

Regards,

Hi there Jack,

there may be ... but this solar max is much lower that the last 3 or 4 maximums
and the spot counts are low in comparison. I would predict that spot levels are not going to be too much different than they have been over recent months. There ISNT likely to be a huge burst in spot numbers just because of the solar magnetic pole flip
Lots of sunspots don't always mean lots of aurora ... ok ... more spots the better chance some of them may produce good flares that result in aurora. But, keep in mind that, the majority of aurora are caused by CME's Coronal Mass Ejections that are not always related to a particular sunspot group. some CME's are flare induced, many are not.

there's been a good number of aurorae even over the last several months.
large aurorae in the past have often been seen from low to mid latitudes, ~ 35North or South depending on what hemisphere you live in.
Where I used to live, at 46S ( SE South Island of New Zealand), I would see the majority of auroral displays, but it also helped that the south magnetic pole was closer to me than in say southern South America or southern Africa.
I'm now in Sydney, Australia area ~ 32S and aurora are almost never seen

Just an additional thought...

after years of aurora observing and photography, I have often found that March and October are among the best months for aurora displays ( the equinox periods)

Further to the previous comments...

Coronal Holes are also a significant source of streams of charged particles that can produce geomagnetic storms and aurora displays

Speaking of which, I have received an email alert today, 14th August, for active to minor storm conditions due to a coronal hole

SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 13/20
ISSUED AT 0005UT/14 AUGUST 2013
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

A coronal hole is rotating into a geoeffective position and is
expected to impact the Earth during the latter half of 14 August
and into 15 August. There is the chance of Minor storm periods
at high latitudes during this interval.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 14-15 AUGUST 2013

cheers

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

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?'

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...
