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 :

Dear all!

I hope everyone here had a smooth transition to 2022! Let's hope this will be be a healthy and exciting year for the HEN observers.

Sorry for being silent for so long (a combination of professional obligations and really bad weather slowed down my astronomy activities to a standstill), but Dave and I as the HEN section leads have worked a bit behind the scenes to plan for some new stuff.

QSO B 0109+224 (S2 0109+224) is in outburst.

In comparison with my last measurements (2021 12 06) there is an increase of almost one magnitude in Sloan g, Sloan r, Sloan i and Johnson V bands.

See AAVSO light cure for details.
