Yesterday I made 2x120s I-band and 1x120s R-band images using a 0.43m reflector of iTelescope.net network at Mayhill, NM, US remotely. Unfortunately the session was aborted, thus no V-band images were made and only a single R-band image.

PGIR21fjn aka AT 2021kgk Sequence is now available
Tim Crawford, Sequence Team
Hello! With my 8" Meade LX200 and ST-402, I get I-filter at 13.8 magnitude with a 2-minute integration and V in mid 17s (but with error of 0.4 mag) with a 3 minute integration. B was too faint with a 5 minute integration.
I've uploaded the I magnitude.
I'll try to increase V integration time or switch to CV when I try tonight. No point in me continuing B-filtered images. Best regards.
Mike

ATel #14574: Spectroscopic confirmation of PGIR21fjn/AT2021kgk as a classical nova outburst
"Overall, the spectrum is consistent with a young classical nova outburst, which peaked at J = 9.1 Vegamag around April 22-23 and has now started to decline, based on the most recent Palomar Gattini-IR data. We encourage further spectroscopic follow-up for this young and rapidly evolving nova."
