On September 8, 2026, I observed the bright supernova SN 2026aaiv in NGC 7331 using remote telescopes of iTelescope.Net. Color photo: 6x240 sec., stacked from the frames obtained with the 0.28-m telescope T68. @astrodave.bsky.social @davidbflower.bsky.social #PhotoHour #StormHour #astronomy #NGC7331
On August 31, 2026, at the 0.43-m remote telescope T32 of iTelescope.Net, I confirmed comet P12pb3b = C/2026 P2 (PANSTARRS); I measured the coma diameter = 6 arcsec. My data: MPEC: www.minorplanetcenter.net/mpec/K26/K26... CBET: www.cbat.eps.harvard.edu/iau/cbet/005... Photo: stacked 9x300 sec.

Before the date (in which we were sadly alone together with my poor mother, - whose anemia is progressing,- because our cat Fanya did not live to see this date - our pet died in 2025): 17 years since I started studying astronomy on self-education (since August 17, 2009), in my housing trouble ...
In the 2026-08-09 photos taken by the Liverpool Telescope for my asteroid searches, I found a possible SN. I checked it in the TNS: this transient AT 2026srj www.wis-tns.org/object/2026srj had been discovered a month earlier. I measured its brightness = 19.7 +/- 0.2 r'. Photo: stacked 6x60 sec.

On 2026-07-18 I observed a comet candidate RMM2026 (from The Possible Comet (and A/ objects) Confirmation Page), remotely using 2-m Liverpool Telescope. My astrometry: RMM2026 KC2026 07 18.01766019 50 39.577-22 16 43.48 21.2 r J13 I stacked 7x60s., did not detect the coma or tail.
I observed the Sun with the unaided eye (through pieces of solar film) from Yuzhno-Morskoy,Nakhodka: 06/29: AR 4478 as 2 distinct dots; 06/30: +AR 4479 as a single elongated, low-contrast spot; 07/01: two spots each in AR 4478 and in AR 4479; 07/02: the same view as on June 30 #PhotoHour #StormHour
On 2026-06-20 I remotely obtained a spectrum of T CrB using the 2-m Liverpool Telescope and submitted to the AAVSO: apps.aavso.org/avspec/obs/2... The intensity of the Hα line appears the same as in 2024. Previous: apps.aavso.org/avspec/obs/1... 2024-06-20 apps.aavso.org/avspec/obs/1... 2025-07-18

It’s getting tough for amateur astronomers to breakthrough with new discoveries. Many have simply took their quest online... but @filipp-romanov.bsky.social was able to nab asteroid 2026 CQ3 last month. Here’s our post on the discovery for @universetoday.com www.universetoday.com/articles/ded...
Dedicated Amateur Beats All-Sky Surveys to Asteroid Discovery
The modern era of all-sky surveys including Pan-STARRS, ATLAS and now the Vera C. Rubin Observatory have given amateur astronomers some stiff competition. But many amateurs have simply upped their gam...

On March 12, 2026, it was a year since the death of our 19.5-year-old cat Fanya. She did not live to see the end of our housing trouble and set off on her last journey, we said goodbye to her forever. More about this: www.facebook.com/romanov.phil... #cat #longlivedcat #pet #astrocat #lastjourney

I observed total lunar eclipse on 2026-03-03 in Yuzhno-Morskoy, Nakhodka, with the unaided eye. The sky was heavily clouded, the Moon was barely visible. My damaged Canon 60D camera stopped working, so I did videos through its viewfinder using a mobile phone camera: attaching the results of stacking
