Alert Notice 637: Nova in Lupus - N Lup 2018 = PNV J15384000-4744500

June 5, 2018

Event: Nova in Lupus - N Lup 2018 = PNV J15384000-4744500

Discovered by: Rob Kaufman (Bright, Victoria, Australia) at White Cliffs, NSW, Australia (via CBET 4520)

Discovery magnitude: 9.1 unfiltered CCD magnitude, object visible in 5 DSLR frames taken with 55mm lens (via CBET 4520)

Discovery date: 2018 June 03.4306 UT (via CBET 4520)

Alert Notice 634: Nightly monitoring requested for V1280 Sco = N Sco 2007

May 11, 2018 : Dr. Frederick Walter (Stony Brook University) has requested AAVSO assistance in monitoring V1280 Sco (Nova Sco 2007).

After it appeared as a nova in February 2007 (AAVSO Alert Notice 346), V1280 Sco reached visual magnitude ~3.8 (several observers), then faded to about 13.2, brightened to about 12.7, and underwent a dust dip in June 2007 to <15.6 V (P. Nelson). It recovered to about 10.3 by about a year later.

Alert Notice 633: Nova outburst of V392 Per = TCP J04432130+4721280

April 30, 2018:

Event: Nova in Perseus - V392 Per = TCP J04432130+4721280

Discovery magnitude: unfiltered CCD magnitude 6.2 (using a 135mm f4.0 lens; via CBET 4515)

Discovery date: 2018 April 29.474 UT (via CBET 4515)

Alert Notice 623: Observations of V1017 Sgr requested

March 16, 2018: Dr. Jennifer Sokoloski (Columbia University) and colleagues (led by Dr. Koji Mukai, NASA Goddard Space Flight Center) have requested AAVSO assistance in observing the nova/dwarf nova V1017 Sgr in preparation for an XMM-Newton observation scheduled for 2018 March 23 or 24.

Confirmation that the system is not in dwarf-nova outburst as of March 23 is needed so that the XMM observation may take place.

March 15, 2018

Event: Nova in Ophiuchus - N Oph 2018 No. 2 = PNV J17140261-2849237 = PNV J17140261-2849237

Discovered Independently by:
- Hideo Nishimura (Kakegawa, Shizuoka-ken, Japan, reported by S. Nakano)

- Koichi Nishiyama (Kurume, Japan) and Fujio Kabashima (Miyaki, Japan)

Alert Notice 620: Coverage of Nova LMC 1996 (OGLE-2018-NOVA-01) outburst needed now

This Alert Notice has been edited to correct a typographical error, and to correct the statement that the LMC was not well placed for coverage from Chile; AAVSO coverage was requested to broaden the coverage in longitude. Apologies for the errors - EOW

March 14, 2018: Dr. Frederick Walter (Stony Brook University) has requested AAVSO observers, particularly those in South Africa, Australia, and New Zealand, to monitor the current outburst of the recurrent nova Nova LMC 1996 = OGLE-2018-NOVA-01.
