If I am trying to capture photometry for a SuperNova event, one of my fears would be over exposing the images. That would be sad: to be on target for the event but then capturing nothing of value.

What if the DSLR was put into a video mode? Is there experience with video-to-fits? That way you could stack your fits images to any SNR you would like.

In the presentations about SNEWS they talk about how amateurs can contribute with DSLR observations.

The advantages are:
-  It would be quick to setup
-  It's 3 color photometry automatically

But there are problems:
- the target might be very bright
- what if comp stars are not available?

I'd like to start a discussion about how to be prepared to do DSLR observations of a SN.

If the event is so bright that it can be done in daylight, how does one calibrate and establish comps?

If you don't already know the Space Telescope Public lecture series, this might be a good reason to explore it:

Astro-Colibri is an application that alerts astronomers in real-time about astronomical transients like GRBs and supernovae. It is very useful if you wnt to get into the habit of being prepared to observe Gamma-Ray-Outbursts, e.g. as targets of opportunity while your observatory is ready doing other tasks.

Astro-Colibri can be used as a web-application, or, perhaps more useful when you want to be alerted in real-time, as a smart phone app for iOS and Android devices.

After suffering the loss of a reaction wheel, the SWIFT satellite was abe to partially resume it's science mission on Feb 17th, but it seems it is still not fully capable to swiftly (forgive me the pun) slew automatically to observe optical Gamma Ray Burst *afterglows*, this leaves an interesting opportunity for us terrestrial observers.

Hi, folks,

An interesting paper on a potential binary SMBH imminent collision was published at: https://arxiv.org/pdf/2201.11633.pdf  recently.

Researcher Dr. Ning Jiang has requested observations in B and V of NSV 6690, the optical AGN of SDSSJ1430+2303.

AAVSO Sequence Team member Chuck Cynamon has updated the sequence and chart for NSV 6690.

Several observers are already contributing data to the database on this object.

Dr. Jiang is especially asking for data from systems with 1 arcsec pixel size or less, but all data is welcome.

Spectra are appreciated.

What a nice way to celebrate the event that happened 35 years ago: the Supernova SN1987A in the LMC :
