Geomagnetic Activity 23rd-26th October 2020

A large coronal hole in the solar north is spewing solar wind across the void of space towards and beyond Earth, creating geomagnetic activity as detected on my magnetometer here in the UK. This is the fourth day of geomagnetic unrest and it seems to be continuing. Maybe a chance to view the aurorae...

Re: SOLARCHAT ZOOM MEETING RECORDING

It’s a shame you couldn’t make it, Mark. You were missed.

Anyhow, it was a great session nevertheless and an excellent opportunity to put faces to names.

Re: Sun in three lights- Sunday 25th October '20

Many thanks, everyone. The lower Sun is presenting greater imaging challenges..... I was struggling to get any sort of sharp definition in Ha and WL.

Sun in three lights- Sunday 25th October '20

A quick set from this morning across the spectrum in Ca II K (393.4nm), Continuum (540nm) and Ha (656.3 nm). Simple FDs (no mosaics) on scopes with 60mm and 72mm objectives because of the conditions. Presented here in mono and false colour. Ca II K showing a few patches of plage https://live.staticf...

Re: DMK41 and Windows 10

Hi Alexandra, Maybe Dell has chosen to limit the output current for low power devices only (typically below 150 mA at 5 Volts). This is too little to power our cameras. The DMK41 requires the port to deliver 500 mA at 5 V, or 2.5 W. USB3 ports are usually able to deliver up to 900 mA, apparently (4....

Just a short animation from October 20th (17 frames) as the seeing conditions were quickly deteriorating during the session (as can be seen during the animation sequence). Colour added in PixInsight.

Re: DMK41 and Windows 10

Hi Alexandra,

Just wondering if it might help to reinstall the camera driver software. Maybe something got corrupted during an update. Just clutching at straws....

Re: Orionids by radio detection

Hi Rainer, It depends how the count rates are calculated, as the apparent hourly rate can vary significantly depending on the time period over which the counts are collected. Can you plot the growth of the cumulative count over a 24 hour period, or send me your data for October 20th and then I can d...

Orionids by radio detection

Radio detected Orionids (Halley's comet debris) which peaked 20/21st October, though detections began sooner (looks like around 14th).

Not as impressive as the Perseids, but detectable nevertheless.

Thanks for looking.
